Step-by-step explanation:

Golden Rule: whatever you do to one side of the equation you do to the other side

x is gonna be used as my representation of a number (x = a number)

3= 5x -2  

flip the equation so the x is on the right side of the equation

move the 2 the other side of the equation

5x  -2   =  3

    +2     +2

5x    = 5

separate the 5 from x by using division

5x/5  = 5/5

x=1

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
