|5y-3|=15 Solve for Y

The two roots are -12/5 and 18/5

Step-by-step explanation:

One way of simplifying the work involved here is to isolate y:  start this by dividing all 3 terms by 5, obtaining:

|y - 3/5| = 3

Then 3/5 is the 'center' and 3 is the distance from this center to each of the two roots.

First root is 3/5 + 3, or 3 3/5, or 18/5.

Second root is 3/5 - 3, or -2 2/5, or -12/5

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

it is 10.6 according to my calculations
