Question

(-2x^2 + wx - 4) - (x^2 + 5x + 6) = -3x^2 - 10

What is the value of w??

Answer 1

Solution for the question asked: 3x^2-5x+4=6

it can be simplified by subtracting 6 from both the sides...

3x^2-5x+4-6=6-6

3x^2-5x-2=0 which is the required form where a=3,b=-5 and c=-2.Now putting the values in the formula we will get two values for x which are 6 and (-1).

hope this will help you

Answer 2

(-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
