Combine like terms, meaning add 12X plus 4X which is 16X and then you add 25Y plus 15Y which equals 40Y so the answer will be 16x+40y. combine like terms means add the ones with the same variable.
(2x+5)(2x+1)
It is equivalent to 3(4x+3y) when factored
x(2x - 3)(x + 4)
12x-4y+9z+2y =12x-2y+9z
16X + 5
4x2+12x = 4x(x+3) when factored
x2-16x+48 = (x-4)(x-12) when factored
15x2+16x-15 = (3x+5)(5x-3) when factored
x2+12x+28Improved Answer:--x2+12x+28 = (-x+14)(x+2) when factored
If you mean: x^2 +12x +20 then it is (x+2)(x+10) when factored
(x + 7)(x + 5)
Combine like terms, meaning add 12X plus 4X which is 16X and then you add 25Y plus 15Y which equals 40Y so the answer will be 16x+40y. combine like terms means add the ones with the same variable.
(2x+5)(2x+1)
It is equivalent to 3(4x+3y) when factored
4x(4x^2 + 3x + 1)
4(1 - 4x + 7y)
