Answer:
vertex = (- 10, - 10 )
Step-by-step explanation:
The equation of a quadratic in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
To obtain this form use the method of completing the square.
Given
h(x) = x² + 20x + 90
add/subtract ( half the coefficient of the x- term )²
h(x) = x² + 2(10)x + 100 - 100 + 90
= (x + 10)² - 10 ← in vertex form
with (h, k ) = (- 10, - 10 )
Make more sense ou of this question and I can help you out more ok?
An equation is a math problem that must be solved to find out to find out a difference, quotient, sum, or product.

Answer:
4 1/15 simpilied MIGHT BE WRONG
Step-by-step explanation:
Answer:
Options A and B
i.e., A. 4(3
) and B.
Step-by-step explanation:
Like radicals are similar to like terms.
For example,
x, 2x, -10x, 
, 7.3x are like terms.
are some more examples of like terms.
Similarly, like radicals are:
etc.
Hence, from the given options, like radicals to 
are:
A. 
and B.
