(-2x)² + wx - 4 + (x)² + (5x + 6) = (-3x)² - 10
Simplify everything.
(-2x × -2x) + wx - 4 + x² + 5x + 6 = (-3x × -3x) - 10
Add / simplify like terms.
4x² + wx -4 + x² + 5x + 6 = 9x² - 10
Add like terms.
(4x² + x²) + 5x + wx + (-4 + 6) = 9x² - 10
Simplify.
4x² + 5x + wx + 2 = 9x² - 10
Get variables to one side.
So, subtract 2 from both sides.
4x² + 5x + wx = 9x² + (-10 + 2)
Then, subtract 9x² from both sides.
(4x² - 9x²) + 5x + wx = -8
Simplify.
-5x² + 5x + wx = -8
~Hope I helped!~
