How can f(x)=6x^2+5x-6 be factored to reveal the zeros of the function it defines

6 x^2+5 x-6
Factor the quadratic 6 x^2+5 x-6. The coefficient of x^2 is 6 and the constant term is -6. The product of 6 and -6 is -36. The factors of -36 which sum to 5 are -4 and 9. So 6 x^2+5 x-6 = 6 x^2+9 x-4 x-6 = 3 (3 x-2)+2 x (3 x-2):
3 (3 x-2)+2 x (3 x-2)
Factor 3 x-2 from 3 (3 x-2)+2 x (3 x-2):
|
| (3 x-2) (2 x+3)
Zeros: 2/3 , -3/2

Answer for 2: his profit would be $2.88 explanation: you have to first multiply 72 and 0.12 together to get $8.64 once you do that you know how much money the shopkeeper made from selling the candy bars individually. so you have to do 8.64-5.76=2.88 hope that ; )answer for 3: yeah i’m sorry i have no idea what number 3 is. i’m sorry i couldn’t with that.
