Here is an easy way to remember, If the discriminant is equal to zero there will be one solution, if the discriminant is less than 0 or negative there are no real solutions, more than 0 or positive there will be two. So one real solution if it is equal

Answer:

\fbox {x-intercepts : (1, 0) and (-3, 0)}

\fbox {Roots : x = 1, x = -3}

Step-by-step explanation:

<u>Given</u> :

  • y = 4x² + 8x - 12

4 cancels throughout.

  • <u>y = x² + 2x - 4</u>

<u>Solving by quadratic formula</u> :

  • x =  -8 ± √(8)² - 4(4)(-12) / 8
  • x = -8 ± √64 + 192 / 8
  • x = -8 ± √256 / 8
  • x = -8 ± 16 / 8
  • x = -1 ± 2
  • x = 1 and x = -3

∴ Hence, the x-intercepts are (1, 0) and (-3, 0). The roots of the equation are 1 and -3.
