NCERT Solutions for Class 10 Maths (Introduction)

Pair of Linear Equations in Two Variables of exercise 4.3( Maths Class 10 ex 4.3) you have studied the following points:

• A quadratic equation in the variable x is of the form ax² + bx + c = 0, where a, b, c are real numbers and a ≠ 0.
• A real number α is said to be a root of the quadratic equation ax²+ bx + c = 0, if aα²+ bα + c = 0. The zeroes of the quadratic polynomial ax²+ bx + c and the roots of the quadratic equation ax²+ bx + c = 0 are the same.
• If we can factorise ax²+ bx + c, a ≠ 0, into a product of two linear factors, then the roots of the quadratic equation ax²+ bx + c = 0 can be found by equating each factor to zero.
• A quadratic equation can also be solved by the method of completing the square.
• A quadratic equation ax²+ bx + c = 0 has: (i) two distinct real roots, if b²– 4ac > 0, two equal roots (i.e., coincident roots), if b²– 4ac = 0, and (iii) no real roots, if b²– 4ac < 0.
