B)
C) D)

4) Solve 3x2 = –12x – 15

A) x = –4 ± 2
B) x = –4 ±
C) x = –2 ± 2 D) x = –2 ±

5) Solve –3x2 + 30x – 90 = 0
A)
B)
C) D)

2. ## Re: Help with some excersises... quadratics...!

2. What effort have you shown to work out these yourself?

3. It is against our policy to do work for a student that counts towards their final grade (as this clearly does).

Show some effort and where you are stuck and you might get some more help.

$x^2 - 3x =-8$
$x^2 - 3x + 8 = 0$

Now you factorize here is link if you do not know how :
