Question

From the sum of 4x² - 2x +6 and 2x² + 4x-1, subtract 5x2 + 2x -4.

Answer 1

Answer:
`\large \boldsymbol {\sf x^2+9 }`

Explanation:

`1) \\\\ \large \boldsymbol {} \sf 4x^2-2x+6 \\ + \\ \underline{2x^2+4x-1} \\\\6x^2+2x+5`
`2) \\\\ \large \boldsymbol {} \sf 6x^2+2x+5 \\-\\ \underline{5x^2+2x-4} \\\\x^2+9`

Answer 2

• x² + 9

Explanation:

Add:

• 4x² - 2x + 6 + 2x² + 4x - 1 = 6x² + 2x + 5

Subtract:

• 6x² + 2x + 5 - 5x² - 2x + 4 = x² + 9
