Multiply the polynomials (5x^2 + 2x +8)(7x7 - 6)

If you mean the "x" is multiply, then your answer is 35x9+14x8+56x7−30x2−12x−48

Explanation:

=(5x2+2x+8)(7x7+−6)

=(5x2)(7x7)+(5x2)(−6)+(2x)(7x7)+(2x)(−6)+(8)(7x7)+(8)(−6)

=35x9−30x2+14x8−12x+56x7−48

=35x9+14x8+56x7−30x2−12x−48

a

step-by-step explanation:

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a
