Answers

Answer:

i think its -4

Step-by-step explanation:

Simplifying

-20x2 = 36x

Solving

-20x2 = 36x

Solving for variable 'x'.

Reorder the terms:

-36x + -20x2 = 36x + -36x

Combine like terms: 36x + -36x = 0

-36x + -20x2 = 0

Factor out the Greatest Common Factor (GCF), '-4x'.

-4x(9 + 5x) = 0

-4.

Simplifying

-20x2 = 36x

Solving

-20x2 = 36x

Solving for variable 'x'.

Reorder the terms:

-36x + -20x2 = 36x + -36x

Combine like terms: 36x + -36x = 0

-36x + -20x2 = 0

Factor out the Greatest Common Factor (GCF), '-4x'.

-4x(9 + 5x) = 0

Ignore the factor -4. ._.
