Storyboard Text

  • What's on your mind James you look like your thinking hard about something.
  • I am thinking about something. How do you find the x values in the equation X^2+3x+2=0.
  • The easiest way to find the x intercepts is through factoring give me 2 numbers when multiplied equals 2 and when added equals 3.
  • Easy positive 2 and positive 1. 2*1=2, 2+1=3.
  • With this info you can now begin changing the equation into factored form.
  • How do I do that Mr.Williams?
  • Easy all you have to do is plug the numbers into the parenthesis
  • The equation in factored form is (x+1)(x+2).
  • Now just set the expression in each set of parenthesis equal to 0. Then solve for x. 
  • In the equation x+1=0, x=-1. In the equation x+2=0, x=-2. Does that mean the x-intercepts are -1,-2
  • Yes -1 and -2 are the x-intercepts
  • Yesssssssssssss i finally understand
