Question

Solve the equation: thank you!
y= 2(x – 3)2 – 50

Answer 1

smallest solution is -2

largest solution is 8

Explanation:

to find the solutions of this quadratic, substitute 0 for 'y' to get:

2(x-3)²-50 = 0

2(x-3)²=50

(x-3)² = 25

x² - 6x + 9 = 25

x² - 6x - 16 = 0

(x-8)(x+2)=0

x = 8, x = -2
