Question

Urgent help please

Which equation has the same solution as x² - 10x - 14 = 4?
(x - 5)² = 43
(x + 5)² = -7
(x + 5)² = 43
(x - 5)² = -7

Answer 1

`(x-5)^2=43`

Explanation:

`x^2-10x-14=4` (Simplify)

`(x-5)^2-25-14=4` (Now add -25 and -14 together)

`(x-5)^2-39=4` (To simplify this down, we will need to add 39 to both sides.)

4+39=43

Therefore, the answer is:
`(x-5)^2=43`.

Hope this helps!
