Question

How do you answer 5X ^2-35

Answer 1

Simplifying 5x2 + -35 = 0
Reorder the terms: -35 + 5x2 = 0
Solving -35 + 5x2 = 0 Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '35' to each side of the equation. -35 + 35 + 5x2 = 0 + 35
Combine like terms: -35 + 35 = 0 0 + 5x2 = 0 + 35 5x2 = 0 + 35
Combine like terms: 0 + 35 = 35 5x2 = 35
Divide each side by '5'. x2 = 7
Simplifying x2 = 7
Take the square root of each side: x = {-2.645751311, 2.645751311}
