y=4x2+3x+8

4x2+3x+6+5x+3x+6 = 4x2+11x+12 when simplified

3x + 2x - 8x + 2x = -x

No, it has factors... 4x2 + 8x -21 = (2x+7)(2x-3)

5x+8x+3x-2x = 14x

-8x

4x2 - 3x - 9

-3x + 1

3x+5y+8x+2y combine 3x and 8x to get 11x 11x+5y+2y combine 5y and 2y 11x+7y is the answer.

ANSWER: -4X2 -8X-4x (x+2)= (-4x * x) + (-4x*2)= -4X2 -8X

It is equivalent to: 3x+6+5 = 3x+11

8x - 23= 3x + 2 +23 +23 8x=3x + 25 -3x -3x 5x=25 x=5 the answer is X=5

3x + 6x - x= 8x

4 + 8x

It is probably 2.

-5y2+3x+2y

8x + 6 = 3x - 4 8x = 3x - 4 - 6 8x = 3x - 10 8x - 3x = -10 5x = -10 5x/5 = -10 x = -10/5 x = -2

4X2+X3+3X+7Y+2X3 can only be simplified to 3X3+4X2+3X+7Y, because X3 and 2X3 are the only like terms.

10 -3x+8x = 25 -3x+8x = 25-10 5x = 15 x = 3

X= -1.8

If: 8x-4 = 3x+21 Then: 8x-3x = 21+4 => 5x = 25 => x = 25/5 Therefore: x = 5

It depends on what it is meant to be equivalent to!

4(x + 1)(x + 1)

4(x^2 + 2x + 8)
