Question

factorise the equation 5a^2-a-30=0 by spitting the middle term plz help me

Answer 1

Given Equation is 5a^2 - a - 30 = 0.

It cannot be factorized by splitting middle term.

It can be solved using Quadratic equations (or) completing square method.

(1)

$= > x = \frac{-b + \sqrt{b^2 - 4ac}}{2a}$

$= > \frac{-(-1) + \sqrt{(-1)^2 + 4 * 5 * 30}}{\2(5)}}$

$= > \frac{1 + \sqrt{{601}}}{10}$

(ii)

$x = \frac{-b - \sqrt{b^2 - 4ac}}{2a}$

$= > \frac{-(-1) - \sqrt{(-1)^2 - 4 * 5 * (-30)}}{2 * 5}$

$= > \frac{1 - \sqrt{601}}{10}$
