Multiply (x-1)(x³+4x²+4x-1) and combine like terms. Explain how you reached your answer.
Hitman42 [59]

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>

(x-1)(x^{3}+4x^{2}  +4x-1)\\=x^4+4x^3+4x^2-x -x^3-4x^2-4x+1

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

x^4+4x^3+4x^2-x -x^3-4x^2-4x+1 = x^4 +(4x^3-x^3)+(4x^2-4x^2)+(-x-4x)+1\\=x^4+3x^3-5x+1

Thus, the answer is x⁴+3x³ -5x +1

What error did zacharias make?
qwelly [4]
The equation 0 = -2x2 5x - 3 was the quadratic formula that Zacharias used. However, he started substituting as:
Quadratic formula as x = ; substitution as x

The errors he made: he mistakenly used the negative (-) and postive (+)
      * -5 should have been 5
      * 52 should have been -52
      * both the numerator and the denominator  should have been -2 instead        of 2
