Super confused definitely need help on this
Marat540 [252]

Answer:

(x-5)(x+8)=x^2+3x-40

Step-by-step explanation:

So we have the expression:

(x-5)(x+8)

To multiply, distribute the left to the terms on the right:

=(x-5)(x)+(x-5)(8)

Distribute:

=(x^2-5x)+(8x-40)

Combine like terms:

=(x^2)+(-5x+8x)+(-40)

Simplify:

=x^2+3x-40

Therefore:

(x-5)(x+8)=x^2+3x-40

Determine the total number of roots of each polynomial function f(x)=3x^6+2x^5+x4-2x^3
Alisiya [41]

Answer:

6 roots

Step-by-step explanation:

f(x)=3x^6+2x^5+x4-2x^3

The number of roots is determined by the degree of the polynomial.  They may be real or complex.

Since this is a 6th degree polynomial, it will have 6 roots

f(x)=3x^6+2x^5+x4-2x^3
