$(x-11)(x+11)$
1. $x^2 +121$
2. $x^2 - 121$
3. $x^2 +22x +121$
4. $x^2 -22x +121$
2.
Multiply. $(x - 5)(2x + 4)$
1. $-6x$
2. $2x^2 - 20$
3. $2x^2 - 26$
4. $2x^2 - 6x - 20$
3.
Multiply: $(6n - 4) (4n + 3)$
1. $12n^2 + 18n - 12$
2. $24n^2 - 2n + 12$
3. $24n^2 + 2n - 12$
4. $10n^2 -16n +12$
4.
Multiply: $(4b + 3) (b - 12)$
1. $4b^2 - 51b -36$
2. $4b^2 + 51b + 36$
3. $4b^2 - 45b - 36$
4. $5b^2 -45b -36$
5.
Multiply: $(x + 8) (x - 8)$
1. $x^2 + 64x - 64$
2. $x^2 +16x - 64$
3. $2x +64$
4. $x^2 - 64$
6.
Multiply the binomials.
$(x-9)(x+7)$

7.
Multiply: $(x-2)(2x^2-3x-1)$
1. $-2x^3+3x^2+x$
2. $-2x^2+3x+1$
3. $2x^3-7x^2-7x-2$
4. $2x^3+x^2-7x-2$
5. $2x^3-7x^2+5x+2$
8.
Multiply: $(x+2)(2x^2-3x+1)$
1. $-2x^3+3x^2+x$
