Question

I WILL UPVOTE U PLEASE HELP ME

Create your own problems that involve subtracting different types of polynomials. Write each problem according to the directions. Then subtract the polynomials, showing all work necessary to write the answer in simplest form.

1. Subtract a first degree binomial from a second degree trinomial.

2. Subtract a second degree trinomial from a second degree trinomial.

3. Subtract a second degree binomial from a third degree trinomial.

Answer 1

1. $(x^{2} +4x+5) - (2x+3)$
$x^{2} +4x+5 - 2x-3$
$x^{2} +(4-2)x+(5-3)$
$x^{2} +2x+2$

2. $(3x^{2} +5x-6)-( x^{2} -3x+2)$
$3x^{2} +5x-6-x^{2} +3x-2$
$(3-1)x^{2} +(5+3)x+(-6-2)$
$2x^{2} +8x-8$

3. $(2x^{3} +4 x^{2} -3x)-(2 x^{2} +6)$
$2x^{3} +4 x^{2} -3x-2 x^{2} -6$
$2x^{3} +(4-2) x^{2} -3x -6$
$2x^{3} +2 x^{2} -3x -6$
