Everything looks right up to . You need to FOIL here. Can you do that?
Can I get some help on this problem, in detail please?
7 { 6 [ 8*( T - 6 ) +12 ] + 2* ( T + 11 ) } ^2
7 { 6 [ 8T - 48 + 12 ] + 2T + 22} ^ 2
7 { 6 [ 8T - 36 ] + 2T + 22} ^ 2
7 { 48T - 216 + 2T + 22} ^ 2
7 { 50T - 194 } ^ 2
7 { 50T^2 - 37636}
{ 350T^2 - 263452}
Is this the correct answer?
