Answer:
(x +4)(x -1)(x +1)
Step-by-step explanation:
The sum of coefficients is zero, so we know that x=1 is a root and x-1 is a factor. We also notice that pairs of terms have coefficients in the ratio 1:4, so x+4 will also be a factor.
= (x+4)(x^2) -1(x+4)
= (x+4)(x^2 -1)
= (x +4)(x -1)(x +1) . . . . . use the factoring of the difference of squares
Answer: Substitution
Step-by-step explanation:
Because you know A is equal to B, you can substitute A for B in any mathematical equation. Essentially, you are switching mA $ mB.
