The roots are 1 +√7 and 1 -√7.
<h3>What is Quadratic equation?</h3>
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.

Answer:
6 neighbors
Step-by-step explanation:
1 bread can be given to 2 neighbors when cut in half(1/2). This case, you have 3 bread so 3x2=6
2t^2+1
Subtract t^2 from 3t^2 you get 2t^2
which is 2t^2+1 answer
