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

2x^2=32 so divide by 2 to make x^2=16 and the square root so x=4
Answer:
8:55
