#### Storyboard Text

• There are 4 more problems to solve.﻿
• 56-35p 7(8-5p)﻿
• Now it's GCF. For this, you have to find the greatest common factor and put it on the outside of the parenthesis and the inside numbers will multiply to match.﻿
• ﻿DOTs, or Difference of two squares, is when you find the square of x and the perfect square of the other number.
• x²-81 (x-9)(x+9)
• ﻿Ok, got it.
• Grouping is when you have a polynomial and you cannot do GCF. What you do is divide the problem into two and solve each one with GCF. Then put the tow GCF's in a parentheis and the multiplied number in another parenthesis.
• 2x²-x²-10x+5 x²(2x-1)  -5(2x-1)  (2x-1)(x²-5)
• x²-81 (x-9)(x+9)
• ﻿Ok, got it.
• Factoring Trinomials is when you find the factors of the number to the right, that add up the number in the middle.
• a²+11a+18 (a+9)(a+2)
• Great. I understand.
• ﻿Thank you so much for the help! Your teaching was great!
