Question

4n2 - 3 = 61
how do I solve by square roots​

Answer 1

n = -4, 4

Explanation:

4n² - 3 = 61

4n² = 64

n² = 16

n = +/- 4

Answer 2

n = 4 or n = -4

Explanation:

We have: 4n² - 3 = 61.

Add 3 to both sides:

4n² = 61 + 3 = 64

Divide both sides by 4:

n² = 64/4 = 16

Square root both sides:

n = +/- √16

n = 4 or n = -4

The answers are 4 and -4.
