Algebra Tiles Activity 1: Adding Integers

NY Standards: 8.A.11; A.A.20; A2.A.7EXPLORING FACTORING POLYNOMIALSIn order to factor polynomials, put your algebra tiles into a rectangular array. You may need toadd zero pairs to complete your model.Ex. Factor x 2 + 4x + 3RearrangeWhat should be on theleft hand side?above?x 2 + 4x + 3 = (x + 1)(x + 3)Factor 2x 2 + 3xRearrange2x 2 + 3x = x(2x + 3)Factor –x 2 + 3x + 4RearrangeNotice I had toadd a zero-pair (x & –x).–x 2 + 3x + 4 = (x + 1)(–x + 4)
