#### Storyboard Text

• 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
