solve:

y(squared)-144=0

please help, for like the other one, i have this on my final too.
Thank You!

y^2-144=0

add 144 to the other side to get:

y^2=144

square root both sides

y=12

what if y were -12 :)

y=12 or y=-12

:(

Nasty quadratics.

To solve the equation y^2 - 144 = 0, we can use the property of taking the square root of both sides of an equation. Here's how you can solve it step by step:

Step 1: Add 144 to both sides of the equation to isolate the square term:
y^2 - 144 + 144 = 0 + 144
y^2 = 144

Step 2: Take the square root of both sides of the equation. Remember that when taking the square root, we consider both positive and negative roots:
√y^2 = ±√144

Step 3: Simplify by finding the square root of 144:
y = ±12

Therefore, the solutions to the equation y^2 - 144 = 0 are y = 12 and y = -12.
