The sum is 28x
68 + 28x - 28 = 236 28x + 68 - 68 -28 + 28 = 236 - 68 + 28 28x = 196 x = 7
.740
5x + 23x + 10 = 28x + 10( ? ? ? )
7x+7=28x 28x-7x=7 21x=7 x=3
49x2+28x+4 = (7x+2)(7x+2) when factored
The sum is 28x
68 + 28x - 28 = 236 28x + 68 - 68 -28 + 28 = 236 - 68 + 28 28x = 196 x = 7
what is -12X squared +28X - 15? i figured it out myself. its (-6X + 5)(2X - 3).
.740
5x + 23x + 10 = 28x + 10( ? ? ? )
7x+7=28x 28x-7x=7 21x=7 x=3
x=35
14x(x + 2)
It can be simplified to: 9-28x
4x2 + 28x + 49 = 4x2 + 14x + 14x + 49 = 2x(2x + 7) + 7(2x + 7) = (2x + 7)(2x + 7) or (2x + 7)2
4x(4x^2 - 6x + 7)
