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:
78.75 cm cubed
Step-by-step explanation:
To find the volume of the prism, use the formula V = l*w*h where l = 4.5, w = 5 and h = 3.5.
So the volume is V = 4.5*5*3.5 = 78.75
Bank A = 1000 x (1 + (0.04*6)) = $1,240
Bank B = 1000 x (1+0.03)^6 = $1,194.05
Bank A would be worth more
