The answer shows the next correct step for solving the quadratic equation by taking the square root of both sides is g-4 = ±√2
<h3>Solving by completing the square method</h3>
Quadratic equations are equation that has a leading degree of 2. Given the quadratic equation as shown below:
g²-8g + 16 = 2
Subtract 16 from both sides
g²-8g + 16 -16 = 2 - 16
g²-8g = -14
Complete the square
g²-8g + (-8/2)² = -14 + (-8/2)²
g²-8g + (-4)² = -14 + (-4)²
(g-4)² = -14 + 16
(g-4)² = 2
Take the square root of both sides
√(g-4)² = ±√2
g-4 = ±√2
Hence the answer shows the next correct step for solving the quadratic equation by taking the square root of both sides is g-4 = ±√2

Answer:
height=100feet
Step-by-step explanation:
perimeter of a rectangle=p=500 feet
p=2a+2b equation 1
a=height
b=base
we have: b/a=3/2
so a=(2*b)/3
in equation 1 we have:
500=2*((2*b)/3)+2*b
so we have
500=(4*b)/3 + 2*b
500=(4b+6b)/3
500=(10b)/3
500*3=10b
b=(500*3)/10
b=150 feet =base
so
a=(2*150)/3=100 feet = height
The cost price of computer=500 dollar
The store manager need a profit of 60%
So the profit amount here=60% of 500=500×
=300
So the store manager should put the price tag=cost price + profit=500+300=800 dollars (Answer)
