3x squared - (3x) squared = 0
5x2 + 3x + 8x2 = 13x2 + 3x = x(13x + 3)
Subtract 5 from each side: 16 = 5x + 3x ie 16 = 8xDivide each side by 8: 2 = x21 = 5x + 3x + 521 - 5 = 8x16 = 8x16/2 = x2 = xx = 2Check:21 = 5(2) + 3(2) + 521 = 10 + 6 + 521 = 21
The given expression can be simplified to: 3X squared +27
3x(6x - 1)
