Answer:
(x - 8)(x + 7)
Zeroes: x = 8, x = -7
Step-by-step explanation:
Find factors of -56 that add to -1.
-8 and 7
The factored form is:
(x - 8)(x + 7)
The zeroes for this polynomial are x = 8 and x = -7
Y-3 is the correct answer
8 to the fourth power is:
8² · 8² =
64 · 64 =
4096
Complete the square since can't factor
2/2=1
add 1 to both sides
x²+2x+1-6=1
factor perfect square
(x+1)²-6=1
add 6 to both sides
(x+1)²=7
sqrt both sides
x+1=+/-√7
minus 1 both sides
x=-1+/-√7
so x=-1+√7 or x=-1-√7
