Factoring with GCF and DOS
2
Learning Intention/Success Criteria
LI: We are learning to factor quadratics using greatest common factor (GCF) SC: I can -recognize if a quadratic can be factored -identify the roots and y-intercept of a quadratic -identify the solutions of the equation by factoring -square and square root numbers -find the GCF -check my work by multiplying binomials

Example 1: Factor the polynomial using GCF
10x2 + 5x First Term: Second Term: 5 • 2 • x • x 5 • 1 • x 5x (2x + 1)
5
Factor the polynomial using GCF: 7x – 21
Guided Practice 1 Factor the polynomial using GCF: 7x – 21 A] Prime B] 7(x – 3) C] 7(x – 21) D] 3(7x – 7) 1st Term: 2nd Term: 7 • 1 • x 7 • 3 7(x – 3)
6
Factor the polynomial using GCF: 16x3 + 24x2 – 8x
Guided Practice 2 Factor the polynomial using GCF: 16x3 + 24x2 – 8x 1st Term: 2nd Term: 3rd Term: 8 • 2 • x • x • x A] 4(4x3 + 6x2 – 2x) B] 4x(4x2 + 6x – 2) C] 8x(2x2 + 3x – 1) D] 2x(8x2 + 12x – 4) 8 • 3 • x • x 8 • 1 • x 8x(2x2 + 3x – 1)
