Once you simplify it, it will become 9x2+5x+40. And, that should make it a little easier. I'm afraid I'm no help after that... hope it helps! :)
Further Information:-
This quadratic espression can't be factored because its discriminant is less than zero.
5(x=8)
Show the terms as additive here..., 8X2 + 10X3 factor out 2X2 2X2(4 + 5X) ---------------- 2X2 ==== greatest common factor
It is: 5x
(x + 5)(x + 8)
5x2 + 3x + 8x2 = 13x2 + 3x = x(13x + 3)
You can factor a five out of 15 plus 5x. Therefore, 15 plus 5x factors out to 5(3+x). Hope it helps :)
It is: 25-4(8*6) = -167
5x
-15x2+5x=-5x(3x-1)
5x+10=40 5x+10-10=40-10 5x=30 5x/5=30/5 x=6
5(x2 + x + 1)
x2 + 13x + 40 = x2 + 5x + 8x + 40 = x(x + 5) + 8(x + 5) = (x + 8)(x + 5)
