1. x^2 - 10x - 24 = 0
(x - 12)(x + 2) = 0 {factor the trinomial}
x = 12, x = - 2 {set each factor to zero}
2. 4x^2 = 11x + 3
4x^2 - 11x - 3 = 0
(4x + 1)(x - 3) = 0
x = - 1/4, x = 3
3. -5x^0
- 5 {any number to the zeroth power = 1}
x^0 = x^n/x^n {any number divided by itself}

1)
(x+2)(x-12)=0
x1=-2
x2=12
2. 4x^2 = 11x + 3
4x^2 -11x - 3=0
(x+1/4)(x-3)=0
x1=-1/4
x2=3
3)-5x^0=-5 if x is not zero.
