5x2 + 25x + 30 This expression describes a parabola, and can be factored out as follows: = 5(x2 + 5x + 6) = 5(x + 2)(x + 3)
2x + 3 + 23x = 25x +3
25x + 35x + 9 is 60x + 9, which factors to 3(20x + 3)
25x + 75 = 25*(x + 3)
The sum is 28x
32 + 25x + 18 = 50 + 25x
5x2 + 25x + 30 This expression describes a parabola, and can be factored out as follows: = 5(x2 + 5x + 6) = 5(x + 2)(x + 3)
25x (square) plus 40 plus 15 equals 680.
2x + 3 + 23x = 25x +3
30x2+25x-24x-20 = 30x2+x-20 = (6x+5)(5x-4) when factored
25x + 35x + 9 is 60x + 9, which factors to 3(20x + 3)
25x + 75 = 25*(x + 3)
The sum is 28x
5x^2(x^2 + 5)
25x-75y+25 = 25(x-3y+1)
25x = 11 so x = 0.44
.25x+3=10 .25x=7 25x=700 x=28
