Write a quadratic that had x-intercepts of -2 and 1/3 show all of your steps

y = 3x² + 5x - 2

Step-by-step explanation:

Given the x- intercepts are x = - 2 and x =

Then the factors are (x + 2) and (x - )

The quadratic is the product of its factors, that is

y = a(x + 2)(x - ) ← a is a multiplier

Expand the factors

y = a(x² + x - )

  let a = 3

y = 3(x² + x - )

  = 3x² + 5x - 2
