(2x - 1)(5x + 8)
That would depend on the plus or minus value of 2 which has not been given.
6-3x = 5x-10x+10 6-3x = -5x+10 -3x+5x = 10-6 2x = 4 x = 2
(5x - 2)(25x^2 + 10x + 4)
x(x2+5x+6)
10x - 5x + 5x = 10x
-10x + 5x = -5x
you don't need to factor, just straight subtraction 5x-10x=-5x
That expression is the square of (5x + 1), so both of its factors are the same.
10x+7 = 5x+32 10x-5x = 32-7 5x = 25 x = 5
If: 10x+7 = 5x+22 Then: 10x-5x = 22-7 And: 5x = 15 So: x = 3
(2x - 1)(5x + 8)
5x + 4 = 10x - 5 10x - 5x = 4 + 5 5x = 9 x = 1.8
That would depend on the plus or minus value of 2 which has not been given.
5x^3(3x + 2)
30 + 5x = 15 + 10x 30 = 15 + 5x 15 = 5x x = 3
15x
