## Question:

Quadratic equations Please Help Me!!!!!!

## Answer:

The **roots **are **1 +√7 **and **1 -√7.**

### What is Quadratic equation?

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.**
