2x^29x5=0
Is it possible to combine 2x squared with 9x?
Not sure how to tackle solving this one.

On these types of questions I always like to do the opposite of the FOIL (First Outer Inner Last) method.
Since the first coefficient is 2 we know we have to have a 2x and an x and then the 5 at the end will result in only 5 and a 1 (one has to be postive and one has to be negative).
This leaves you with
(2x and 1)(x and 5)
OR
(2x and 5)(x and 1)
By process of elimination, I figured out it was (2x+1)(x5)=0.
You can then set each equation equal to 0 and solve for x.

Can someone check my answer please! I'm not sure this is right x(squared)+7x+10=0 (x+r)(x+s) =x(squared)+sx+rx+rs =x(squared)+(r+s)x+rs x(squared)+(r+s)x+rs=x(squared)+7x+10 r+s=7 rs=10 (2)(5)=10 and 3+4=7 x(squared)+7x+10=(x+5)(x+2)
