Answer:
D
Step-by-step explanation:
I'm not 100% sure but since when you remove the square roots on a and b, you have to add it to X
The answers for these solutions to equation (x - 21)^2 = 25 are
x = 26
x =16
Picture proof
Answer:
5^11
Step-by-step explanation:
-5^5 ÷ -5^-6
5^5 divide 5^-6
5^11
<span>The general equation of a quadratic is expressed as y = ax^2+bx+c. To
convert the general equation to vertex form, we need to obtain this form:
(y- k)= a(x - h)^2
This could be done by using completing the square method.
</span><span>y = –3x^2 – 12x – 2
</span><span>y + 2 = –3(x^2 + 4x)
</span>y + 2 -12 <span>= –3(x^2 + 4x + 4)
</span>y - 10 = -3(x+2)^2
Therefore, the answer is the first option.
