Question

Find the roots of x^2+x-30=0 *​

Answer 1

Answer:

$x {}^{2} + x - 30 = 0 \\ = > x { }^{2} + 6x - 5x - 30 = 0 \\ = > x(x + 6) - 5(x + 6) \\ = >( x - 5)(x + 6) = 0 \\ = > x = 5 \: \: \: \: \: \\ x = - 6$

Answer 2

Step-by-step explanation:

x^2+x-30=0

x^2+(6-5)x-30=0

x^2+6x-5x-30=0

x(x+6)-5(x+6)=0

(x+6)(x-5)=0

x=-6 or x=5

So roots of the given equation are -6 and 5
