Question

Can someone show me how to get the answer to this step by step? It's Combining Like Terms.
`-9x^(2)` - 7 +
`4x` +
`10x^(2)` - 14x

Answer 1

x² - 10x - 7

Explanation:

See steps below:

• - 9x² - 7 + 4x + 10x² - 14x =
• (-9x² + 10x²) + (4x - 14x) - 7 = ⇒ like terms combined in parenthesis
• x² - 10x - 7 ⇒ simplified
