Multiply (3x - 4y)(2x + 5y)
6x^2 + 7xy - 20y^2
6x^2 - 7xy - 20y^2
6x^2 + 7xy + 20y^2
Subtract: (r^2 - 2r - 5) - (3r^2 - 5r + 7)
2r^2 - 3r - 12
-2r^2 + 3r - 12
-2r^2 - 8r + 2
To factor 5x + 20, I would divide each term by 5, for a final answer of 5(x + 4)?
Factor: x^2 + 7x + 12
(x + 6)(x + 2)
(x + 12)(x + 1)
(x + 3)(x + 4)
Factor: 8a^2 - 26a + 15
