In mathematics, a square root of a number x is a number y such that y2 = x; in other words, a number y whose square (the result of multiplying the number by itself, or y ⋅ y) is x. For example, 4 and −4 are square roots of 16 because 42 = (−4)2 = 16.
Answer:
C
Step-by-step explanation:
We want to solve the equation:
Using the quadratic formula. The quadratic formula is given by:
In this case, <em>a</em> = 1, <em>b</em> = 2, and <em>c</em> = 7.

<u>ANSWER</u>
<u>EXPLANATION</u>
We have
.
Expressing in terms of means we should rewrite the relation such that will remain on one side of the equation while and any other constant will be at the other side.
To make the subject, we add to both sides of the equation.
.
we now multiply the whole equation by the reciprocal of the coefficient of , which is .
This implies that;
This simplifies to;
