How to Solve an Algebraic Equation?

To solve an algebraic equation, isolate the variable in the equation. Its value is the solution.

Given the following algebraic equation:

2x(x + 1.5) = -1

Open bracket

2x² + 3x = -1

2x² + 3x + 1 = 0

Factorize

2x² + 2x + x + 1 = 0

(2x² + 2x) + (x + 1) = 0

2x(x + 1) +1(x + 1) = 0

(2x + 1)(x + 1) = 0

2x + 1 = 0

2x = -1

x = -1/2

Or

x + 1 = 0

x = -1

Therefore, the solution to the given algebraic equation is: x = -1/2 or x = -1.
