Question

What is x^2 - 6 = 16x + 30 rewritten in standard form, than factored?

Answer 1

x=8+2√7 or x=8−2√7

Explanation:

x^2 - 6 = 16x + 30

X² = 16x +30 + 6

X² - 16x - 36 = 0

For this equation: a=1, b=-16, c=36

1x² + −16x +36=0

Step 1:

Use quadratic formula with a=1, b=-16, c=36.

x= −b±√b2−4ac/2a

x=(−(−16)±√(−16)2−4(1)(36))/2(1)

x= (6±√112)/2

x=8+2√7 or x=8−2√7
