If the hypotenuse is 13 cm, find the other two sides. Let the length of the base of the triangle be. Then, the altitude length will sllutions. Given if hypotenuse is. Applying the Pythagoras theorem; we. But, the length of the base cannot be negative.

Hence the base length will be. Therefore, we clqss. Altitude length and Base length. Q6 A cottage industry produces a certain number of pottery articles in a day. It was observed on a particular day that the cost of production of cahpter article in rupees was 3 more than twice the number of articles produced on that day.

If the total cost of production on that day was Rs 90, find the hcapter of articles produced and the cost **ncert solutions of chapter 4 class 10th maths** each article. Let the number of articles produced in **ncert solutions of chapter 4 class 10th maths** day. The cost of production of each article will be.

Given the total production on that day. Hence we soluhions the equation. But, x cannot be negative as it is the number of articles. Therefore, and the cost of each article. Hence, the number of articles is 6 and the cost of each article is Rs. Q1 i Find the roots of the following quadratic equations, if they exist, by the method of completing the square.

Solutoons equation:.

When a quadratic polynomial is equated to zero, it is called a quadratic equation. A zero of a polynomial is that real number, which when substituted for the variable makes the value of the polynomial zero. In case of a quadratic equation, the value of the variable for which LHS and RHS of the equation become equal is called a root or solution of the quadratic equation. There are three algebraic methods for finding the solution of a quadratic equation.

Brahmagupta an ancient Indian Mathematician A. Later Sridharacharya A. An Arab mathematician Al-khwarizni about A. It is believed that Babylonians were the first to solve quadratic equations. Greek mathematician Euclid developed a geometrical approach for finding lengths, which are nothing but solutions of quadratic equations.

The formulas are not easy to learn, and students don't catch tricks easily where they should apply. Chapter 4 Maths Class 10 contains quadratic equations to find the value of x. Apart from this, there are approximately three methods given in Class 10 Maths Chapter 4 for this. But, not all three methods are easy to understand to an individual. All concepts of quadratic equations and formulas have been explained well.

From where the formula comes, how it is discovered, by whom it is discovered, and many other things are mentioned first for the basic knowledge.

For the ease of the students, it is also mentioned which question came in which year. Some of the mock test papers are also available at the end of pdf for the students' better preparation.
