Question

how to solve 2x^2-27​

Answer 1

Answer:

Simplifying

2x2 + -27 = 0

Reorder the terms:

-27 + 2x2 = 0

Solving

-27 + 2x2 = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '27' to each side of the equation.

-27 + 27 + 2x2 = 0 + 27

Combine like terms: -27 + 27 = 0

0 + 2x2 = 0 + 27

2x2 = 0 + 27

Combine like terms: 0 + 27 = 27

2x2 = 27

Divide each side by '2'.

x2 = 13.5

Simplifying

x2 = 13.5

Take the square root of each side:

x = {-3.674234614, 3.674234614}
