hey, i've been going through an exam paper but i can't solve the last question!:
solve the simultaneous equations - y=x(squared) -3x and y=2x-6
i got up to the factorization bit i can't find any numbers that fit in with it and i can't use the quadratic formula because its a non-calc paper!
any help? :)
i know but it's a non-calc paper so i wouldn't be able to do that in the actual exam!
x= 3 or 2
thank you so much!! :)
you could use the quadratic formula to find out what x equals!
