### What is the factor of the trinomial below negative x2 plus 12x plus 28?

I would do this. Multiply through by -1 -1 ( -X^2 +12X +28 ) = X^2 -12X -28 (X+2)(X-14)

-(x - 14)(x + 2)

### How factor -2x plus 12x plus 28?

-2x+12x+28=10x+28 ;Combining like factors2(5x+14) ; Factor out a two from both of them

### 12x-28 equals -63 plus 7x?

12x - 28 = 7x - 63Subtract 7x from each side:5x - 28 = -63Add 28 to each side:5x = -35Divide each side by 5:x = -7

### X2 - 16x plus 28 binomials trinomial?

That factors to (x - 14)(x - 2)
