(3x² + 2xy + 4y²) + (6x² - 5xy + 3y²) + (9y² - 25y²)
Get rid of the parenthesis :)
3x² + 2xy + 4y² + 6x² - 5xy + 3y² + 9y² - 25y²
Add like terms.
(3x² + 6x²) + (2xy - 5xy) + (4y² + 3y² + 9y² - 25y²)
Simplify.
(9x²) + (-3xy) + (-11y²)
Get rid of the parenthesis.
9x² - 3xy - 11y²
~Hope I helped!~
The answer will be 6(3)-4-32
Each number is 4 times the previous number"
2*4 = 8
8*4 = 32
32*4 = 128
so next 3 are:
128 * 4 = 512
512*4 = 2048
2048 * 4 = 8192
512 , 2048, 8192
