(-2x^2 + wx - 4) - (x^2 + 5x + 6) = -3x^2 - 10 what is the value of w? ?

(-2x² + wx - 4) - (x² + 5x + 6) = -3x² - 10    Distribute/multiply - into (x² + 5x + 6)

-2x² + wx - 4 - x² - 5x - 6 = -3x² - 10      Combine like terms

-3x² + wx - 5x - 10 = -3x² - 10         Add 10 on both sides

-3x² + wx - 5x = -3x²               Add 3x² on both sides

wx - 5x = 0          Add 5x on both sides

wx = 5x        Divide x on both sides

w = 5

okay wait before i answer, is this for your points on a graph?

answer: 0.26

i used the calculator on google
