In the expression

$6x^2+7x+2$

we would re-write 7x using two terms that are

• both positive

• both negative

• one positive and one negative

In the expression

 $2-x-x^2$ 

we would re-write -x using two terms that are

• both positive

• both negative

• one positive and one negative

In the expression

 $4x^2-11x+6$ 

we would re-write  -11x using two terms that are

• both positive

• both negative

• one positive and one negative

In the expression

 $3x^2-11x-20$ 

we would re-write -11x using two terms that are

• both positive

• both negative

• one positive and one negative
