Question

How do I get the answer for this quadratic equation in simplest form?

Answer 1

Answer:

x = 7 ± $\sqrt{15}$

Step-by-step explanation:

Given

4(x - 7)² - 48 = 12 ( add 48 to both sides )

4(x - 7)² = 60 ( divide both sides by 4 )

(x - 7)² = 15 ( take the square root of both sides )

x - 7 = ± $\sqrt{15}$ ( add 7 to both sides )

x = 7 ± $\sqrt{15}$
