(-4w² - 9n) - (-15w²)
Treat the minus sign in the middle as if it's -1 and distribute.
(-4w² - 9n) -1(-15w²) = (-4w² - 9n) +15w²

Take out parentheses -4w² - 9n +15w²
Combine like terms. Two of these terms have a w² so we put them together

11w² - 9n
That's as simplified as it could get

What is the value of x (x+2)(x-3)=0
wolverine [178]

Answer:

x = 3 or x = -2

Step-by-step explanation:

Solve for x over the real numbers:

(x + 2) (x - 3) = 0

Hint: | Find the roots of each term in the product separately.

Split into two equations:

x - 3 = 0 or x + 2 = 0

Hint: | Look at the first equation: Solve for x.

Add 3 to both sides:

x = 3 or x + 2 = 0

Hint: | Look at the second equation: Solve for x.

Subtract 2 from both sides:

Answer: x = 3 or x = -2
