Question

I need to simplify this
(3a^2+2ab+4b^2) + (6a^2-5ab+3b^2) + (9b^2-25b^2)

Answer 1

(3a² + 2ab + 4b²) + (6a² - 5ab + 3b²) + (9b² - 25b²)

Get rid of the parenthesis :)

3a² + 2ab + 4b² + 6a² - 5ab + 3b² + 9b² - 25b²

Add like terms.

(3a² + 6a²) + (2ab - 5ab) + (4b² + 3b² + 9b² - 25b²)

Simplify.

(9a²) + (-3ab) + (-11b²)

Get rid of the parenthesis.

9a² - 3ab - 11b²
