Jack is learning to save, spend, and give his money away. He has determined to give away 10% of his summer job earnings. If he gives away $256, how much money did he earn this summer?

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer

first one is a: renaming a fraction. second one is c: de-c
