Q1 of 58 Page 118

Find the roots of the following quadratic equation if they exist.

5x2 - 7x - 6 = 0

5x2 - 7x - 6 = 0

The equation is of the form ax2 + bx + c = 0


Since a≠0 ,so it exists


We use the method of factorization to solve it


⇒ 5x2 - 10x + 3x - 6 = 0


⇒ 5x(x - 2) + 3(x - 2) = 0


⇒ (5x + 3)(x - 2) = 0


⇒ x
