Answer:
<em>64 ; 8</em>
Step-by-step explanation:
a² ± 2ab + b² = (a ± b)²
x² + 2(8)(x) + 8² =
x² + 16x + <em>64</em> =
(x + <em>8</em>)²
Answer: 2

Answer:
Step-by-step explanation:
We want to find the polynomial function whose zero are -1 and 4i.
Recall that non-real zeros come in pairs.
There if 4i is a zero, then the conjugate -4i is also a zero.
Therefore the factors of this polynomial are:
x+1, x+4i, and x-4i are factors of the given polynomial.
Let f(x) be the required polynomial, then we can write the polynomial in factored form as:
We expand the conjugate pair using difference of two squares to get:
Expand further using the distributive property to get:
The square root of 1,000,000 is 1,000.

Answer:
172
Step-by-step explanation:
