(5x - 3)(7x + 9)
The quadratic 4x2+24x+11 = (2x+1)(2x+11)
If you can't factor it easily, use the quadratic formula.
factor the trinomial 16x^2+24x+9
24x^5 + 24x^3 = 24x^3(x^2 + 1)
x2 + 24x +180 = 0 By using the quadratic equation, you can find that x = -12 + 6i or x = -12 - 6i
It is a quadratic expression in the variable x.
12x^2+24x+12 12(x^2+2x+1) 12(x+1)^2
6x(3x2 - x + 4)
(3x + 4)(3x + 4)
3x(x - 2)(x - 4)
(4x + 3)(4x + 3) (4x + 3)2
Let the symbol ^ mean "to the power" Then 9x^2 + 24x + 16 = (3x + 4)(3x +4) = (3x + 4)^2
