Write the polynomial expression: 5x+4x^2(2x+7)-(6x^2-9x) in standard form.

Question

Help please. Thank you. And stay safe.

Answer 1

1.) Distribute 4x².

2.) Distribute -1.

3.) Combine like terms and then write the expression in standard form.

5x + 4x²(2x + 7) - (6x² - 9x) = 5x + 8x³ + 28x² - 6x² + 9x

= 8x³ + 22x² + 14x
