Answer 2

EXPLANATION.

Roots of the quadratic equation.

⇒ x² - 3x - 10 = 0.

As we know that,

Factorizes the equation into middle term splits, we get.

⇒ x² - 5x + 2x - 10 = 0.

⇒ x(x - 5) + 2(x - 5) = 0.

⇒ (x + 2)(x - 5) = 0.

⇒ x = - 2 and x = 5.

                                                                                                                         

MORE INFORMATION.

Nature of the roots of the quadratic expression.

(1) = Real and unequal, if b² - 4ac > 0.

(2) = Rational and different, if b² - 4ac is a perfect square.

(3) = Real and equal, if b² - 4ac = 0.

(4) = If D < 0 Roots are imaginary and unequal Or complex conjugate.
