Level:
B
Factor the expression: \[(2 - b)(b -7) - 5(b -7)(2b - 3) - (7 -b)^2\]
\(12(b - 7)(2 - b)\)
\(12(b - 7)(b - 2)\)
\(10(b - 7)(1 - b)\)
\(10(b - 7)(b - 1)\)

Level:
B
Factor the expression: \[(4 + a)(a - 3) - (3 - a)^2 - 3(a - 3)(2a + 1)\]
\(2(a - 3)(2 - 3a)\)
\(2(a - 3)(3a - 2)\)
\(2(3 - a)(2a + 1)\)
\(2(a - 3)(2a + 1)\)
