Jawaban:
[tex]16). \: \frac{5x + 20 + 6x + 18}{ {x}^{2} + 7x + 12 } = \frac{11x + 38}{ {x}^{2} + 7x + 12} \\ \\ [/tex]
[tex]17). \: (3x - 4)(3x - 4) = \\ {9x}^{2} - 12x - 12x + 16 = \\ {9x}^{2} - 24x + 16 \\ \\ 2(9) - 3( - 24) - 4(16) = \\ 18 + 72 - 64 = 26 \\ \\ [/tex]
[tex]18). \: 2(2) - 5(5)(1) = 4 - 25 = - 21 \\ \\ 19). \: \frac{2x + 6 + x - 1}{2x} = \frac{3x + 5}{2x} \\ \\ [/tex]
[tex]20). \: (\frac{1}{2} {a}^{2} {b}^{3} )(\frac{1}{2} {a}^{2} {b}^{3} ) = \frac{1}{4} {a}^{4} {b}^{6} [/tex]
