The multiple Choises of number 3 are
A- b^2 - 18b + 81
B- -b^2 - 18b + 81
C- b^2 - 9b + 81
D- b^2 + 81

1. 4x^2 + 29x - 24
2. (2x - 9)(x + 2)
3. 81 - 18b + b^2
4. (13 + 12c)(13 - 12c)
These were easy, you should try harder.

1: FOIL...TOO EASY
2. QUADRATIC OR RECGULAR FACTORIZATION
3. BINOMIAL USE THE PROPERTY A^2 - 2A*B+B^2
4. REARRANGE IT TO
-144C^2 + 169......USE THE QUADRATIC EQUATION TO GET THE ANSWER (-12C - 13) (12C -13)
REMEMBER (-12C - 13) (12C -13) = (13+12C) (13 - 12C)
WHERE A' = -144 B' = 0 C'= 169...GOOD LUCK
