Answer:
(x+9)(x+4)
Step-by-step explanation:
We wish to factor x²+13x+36 into the form of (x+p)(x+q) where p+q=13 and pq=36.
Factors of 36: 1, 2, 3, 4, 6, 9, 12. 18, 36
Notice that 9+4=13 as 9*4=36, which satisfies the values of p and q
This means x²+13x+36 can be factored into (x+9)(x+4)
1) 2x = +/- 4 so x = +/- 2
2) x-3 = 7 OR x - 3 = -7
so x = 10 or x = -4
3)2x + 5 = 21 OR 2x + 5 = -21
so x = 8 or x = -13
4) x + 4 = 6 OR x + 4 = -6
so x = 2 or x = -10
5) x + 2 = -(2x+4) OR x + 2 = 2x + 4
x = -2 or x = -6
6) x + 7 = 0
x = -7
7) you forgot the equal sign somewhere in this problem

Answer:
A
Step-by-step explanation:
y=2(x-3)^2-3
replace x for x in the table
so y=2(1-3)^2-3
-2*-2
4*2
8-3
y=5
just like in the table
