What are the solutions for x when y is equal to 0 in the quadratic function y=x^2-8x

Elena L [17]

I would use the quadratic formula for this:

x = -b ± √b² - 4ac over 2a
x = 8 ± √64 - 4(1)(0) over 2(1)
x = 8 ± √64 over 2
x = 8 ± 8 over 2 [simplify]
x = 4 ± 4
x1 = 4 + 4 x2 = 4 - 4
x1 = 8 x2 = 0

Thus, the solutions for x would be 0 and 8.

The answer is $10

if you add up the total price for each of the items it totals to $40, she has $50 so $50-$40=$10
