These are are one of the answer and question example that you would probably utilize to practice and enhance your understanding and also give you insights that might help you to keep up your study in school.

## Question:

The roots are 1 +√7 and 1 -√7.

A quadratic equation in the variable x is an equation of the form ax² + bx + c= 0, where a, b, c are real numbers, a≠0

Given equation:

y= x²+2x-6

First,

Half the coefficient of x and add and subtract the square of (b/2)

y= x²+2x-6+(1)²-(1)²

y= x²+2x+(1)² -6 -(1)²

y= (x+1)² -7

Now, equate y=0

(x+1)² -7 =0

(x+1)² = 7

x+1= ±√7

x=1 ±√7

Hence, the roots are 1 +√7 and 1 -√7.

They may hopefully help the student answer the question by making use of the questions and answer examples. You could simply then have a discussion with your classmate and continue the school learning by studying the subject altogether.
