Question 1030164
Hi there,
You are correct with your
factorisation
x^2 - 13x - 30 
= (x - 15)(x + 2)
To get the values for x
you make x^2 - 13x - 30 = 0
(as you did)
So,
(x - 15)(x + 2)= 0
Take each separate bracket:-
x - 15 = 0
x = 15
x + 2 = 0
x = -2
So values for x are:-
x = -2, 15.
Hope this helps :-)
