Squaring Polynomials To square something means to multiply it by itself. To square a polynomial, multiply it by itself!! (x + 2)2 (x + 2)(x + 2)
( x + 2)2 ( x + 2)( x + 2) x2 + 2x + 2x + 4 x2 + 4x + 4
(2x + 3)(2x + 3) 1. (2x + 3)2 4x2 + 6x + 6x + 9 4x2 + 12x + 9
(3x – 5)(3x – 5) 2. (3x – 5)2 9x2 – 15x – 15x + 25 9x2 – 30x + 25
(3 – 5x)(3 – 5x) 3. (3 – 5x)2 9 – 15x – 15x + 25x2 9 – 30x + 25x2 25x2 – 30x + 9
