It is an expression that can be simplified to: 4x2-42
x2 + x2 + x2 = (1 + 1 + 1)x2 = 3x2
x2 + x2 = 2x2
3x4 plus 5x3 plus x2 - 5 divided by x 2 =[(3x4) + (5x3) + (x2 - 5)]/x2 =(12 + 15 + x2 -5)/x2 =(27 - 5 + x2)/x2 =(22 + x2)/x2
x2 + 48x + 320
x2 + x2 = 2x2
x4 +x2 =x2 (x2+1)
4x2 + x2 = 8 + x2
x3 + x2 + 4x + 4 = (x2 + 4)(x + 1)
You cannot solve, without equating it to something. As given it is just an expression. However it can be factored. x^(2) + 7x +12 ( x + 3)(x + 4) Factored but NOT solved. However, it we equate to 'zero(0)' then it can be solved. ( x + 3)( x + 4) = 0 X + 3 = 0 x = -3 Similarly x + 4 = 0 x = -4 Are the solutions (solved).
