4n2 - 3 = 61

how do I solve by square roots

n = 4 or n = - 4

Step-by-step 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.

n = - 4, 4

Step-by-step explanation:

4n² - 3 = 61

4n² = 64

n² = 16

n = + / - 4
