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.
