3(x2 + 3x + 1)
3x2 + 10x + 3 = (x + 3)(3x + 1).
9x2 + 6x + 1 = 9x2 + 3x + 3x + 1 = 3x(3x + 1) + 1(3x + 1) = (3x + 1)(3x + 1) or (3x +1)2
In one bracket, write 16 times the square root of 2 minus 3x. In the other one, write 16 times the square root of 2 plus 3x.
3X2 - 3X 3X(X - 1) -----------------------factored, so 3X is gfc
3x2 -14x -24 can be factored as (3x + 4)(x - 6).
3x^2 -14x +15 = (3x-5)(x-3)
3x/7 + 5y/14x = 3x*2x/(7*2x) + 5y/14x = (6x2 + 5y)/14x
2x(x2 + 3x - 7)
(3x + 1)(x - 5)
(14x-2y)+(7x-3y)+(-3x) = 14x-2y+7x-3y-3x =(14+7-3)x-(2+3)y =18x-5y
5x+8x+3x-2x = 14x
yes, and it is 14x
-11
5x2 + 3x + 8x2 = 13x2 + 3x = x(13x + 3)
The given expression can be simplified to: 3X squared +27
5x^2 + 14x - 3x^2 - 9 = 2x^2 + 14x - 9
