Answer:
x⁴+3x³ -5x +1
Step-by-step explanation:
To multiply this we are going to <u>multiply each term of the binomial by each term of the polynomial.</u>

Now we are going to <u>combine like terms (this means we are going to sum up terms with the same exponent)</u>

Thus, the answer is x⁴+3x³ -5x +1
Answer:
x = -3
Step-by-step explanation:
5 x + 3 = 4 x
Solve for x
5x - 4x + 3 = 0
x + 3 = 0
x = -3
Put the value where the variable is and do the arithmetic.
f(-4) = -5(-4) +(-4)/(-2)
= 20 + 2
= 22
The appropriate choice is
