Answer 1

Answer:

factor quadratic x^2-7x+12; expand polynomial (x-3)(x^3+5x-2) GCD of x^4+2x^3-9x^2+46x-16 with x^4-8x^3+25x^2-46x+16; quotient of x^3-8x^2+17x-6 with x-3; remainder of x^3-2x^2+5x-7 divided by x-3; roots of x^2-3x+2

:D

Answer 2

Step-by-step explanation:

If x+5 is a factor of x³+13x²+ax+35, then x = -5 is a zero of the given polynomial, that is if you substitute -5 in place of x, you must get value 0
