Identify GCF: Identify the greatest common factor (GCF) of the terms 242g2 and 288. The GCF of 242 and 288 is 2.
Divide and Simplify: Divide each term by the GCF to find the simplified expression.(242g2÷2)−(288÷2)=121g2−144
Recognize Perfect Squares: Recognize that 121g2 is a perfect square (11g)2 and 144 is also a perfect square 122. We can now express the equation as a difference of squares: (11g)2−(12)2.
Factor Difference of Squares: Factor the difference of squares using the identity a2−b2=(a+b)(a−b). The factored form is (11g+12)(11g−12).
