Question

-5X^2 + 3X = -3X^2 + 3X - 50  solve for x ​

Answer 1

X = 5, —5

Explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer 2

`-5x^2+3x = -3x^2 +3x -50\\\\\implies 5x^2-3x^2 +3x-3x -50 =0\\\\\implies 2x^2 -50 =0\\\\\implies x^2 -25 = 0\\\\\implies x^2 = 25\\\\\implies x = \pm5\\\\\text{Hence}~ x = 5~ \text{or}~ x = -5`
