steps of 3(x+6) ^2 =75

Answer 1

Hi Anjali,

3(x+6) ^2 =75

first of all 3(x+6) ^2 =75 both side divided by 3

(x+6) ^2 =25 square root of both side

(x+6) = ± 5 now solve this equation one time with 5 another with -5

1) x + 6 = 5 both side minus 6

x = 5 - 6 = -1

2) x + 6 = -5 both side minus 6

x = -5 -6 = -11

answers are -1 and -11

I hope it is useful,
