Hey I have my final exam today and I was looking over my review and found a problem I would like explained if anyone could assist with that.

Solve the equation:
x^2 + 7x - 60 = 0
(The answers are x = -12 and x=5)

Just a breakdown of how to work it out would be great!

well by the looks of it you just do -12^2 + 7x5 or times 5 - 60 = 0 (tho i dont know what ^ means im only in 6th)

anonymous · Answer

$$(x-5)(x+12)=x^2+7x-60=0$$
multiply x times x to get    x squared         x times 12 to get 12x 
multiply -5 times                                              x=-5x  and -5 times 12=-60
put these together x^2+7x-60

Thanks Jamaica :)

@RyanM.Freeman ^ means to the power of. It's just easier to use than to go and find a squared symbol.
