what are the solutions to the following equation 3x^2+5=80?
I THINK ITS
3x^2 = 75
x^2 = 25
x=+5 or x=-5
THANKKK YOU!!!!
To find the solutions to the equation 3x^2 + 5 = 80, we need to rearrange the equation to isolate x.
Step 1: Start by subtracting 5 from both sides of the equation:
3x^2 + 5 - 5 = 80 - 5
3x^2 = 75
Step 2: Divide both sides of the equation by 3 to solve for x^2:
(3x^2)/3 = 75/3
x^2 = 25
Step 3: Take the square root of both sides of the equation to find the values of x:
√(x^2) = √25
x = ±5
So, the solutions to the equation 3x^2 + 5 = 80 are x = 5 and x = -5.
