Answer :
Step 1. Rewrite it in the form: [tex] a^{2} - b^{2} [/tex], where a = y and b = 13
[tex] y^{2} - 13^{2} [/tex]
Step 2. Use Difference of Squares: [tex] a^{2} - b^{2} =(a+b)(a-b)[/tex]
[tex](y+13)(y-13)[/tex]
Done!
[tex] y^{2} - 13^{2} [/tex]
Step 2. Use Difference of Squares: [tex] a^{2} - b^{2} =(a+b)(a-b)[/tex]
[tex](y+13)(y-13)[/tex]
Done!
