Simplify: (4x² – 3x + 8) – (3x2 – 5)

x^2+−3x+13

Step-by-step explanation:

simplify step-by-step.

4x^2−3x+8−(3x^2−5)

Distribute the Negative Sign:

=4x^2−3x+8+−1(3x^2−5)

=4x^2+−3x+8+−1(3x^2)+(−1)(−5)

=4x^2+−3x+8+−3x2+5

Combine Like Terms:

=4x2+−3x+8+−3x^2+5

=(4x^2+−3x^2)+(−3x)+(8+5)

=x^2+−3x+13

answer: i think it's a

step-by-step explanation:

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
