Question

Can you help me with -5x^2+18x+8? (Its number 34.)

Answer 1

34. -5x² + 18x + 8
-5x² + 20x - 2x + 8
(5x + 2)(-x + 4)

37. -12x² + x + 20
-12x² + 16x - 15x + 20
(4x + 5)(-3x + 4)

Answer 2

you do -5x^2  which gives you 25x and then you add 18x to 25x which will give you 43x and then you are left with 43x+8.
