Answer:

  \\ x ^{2}  + 11x + 18 \\  \\ x ^{2}  + 9x + 2x + 18 \\  \\ x(x + 9) + 2(x + 9) \\  \\ (x + 2)(x + 9) \\  \\ x =  - 2 \:  \: x =  - 9 \\  \\ so \: the \: zeroes \: of \: p(x) are \:  - 2 \: and \:  - 9 \\  \\ <u>sum \: of \: zeroes = ( - 2 + ( - 9)) </u>\\  \\  \:  \:  \:  \:  =  - 11 \\  \\ <u>product \: of \: zeroes = </u> - 2 \times  - 9 \\    \:  \:  \:  \:  \:  \:  = 18   \\  \\  b)we \: have \:  \\  \\ 2x ^{2}  + x - 6 \\  \\  2x ^{2}  + 4x - 3x - 6 \\  \\ 2x(x + 2) - 3(x + 2) \\  \\ (2x - 3)(x + 2) \\  \\ x =  \frac{3}{2}  \:  \: x =  - 2 \\  \\ so \: the \:<u> zeroes \: of \: f(x) \: are</u> \<u>frac{3}{2} and \:  - 2 \</u>\  \\ sum \: of \: zeroes \:  =  \:  \frac{3}{2}  +  - 2 \\   =   \frac{ - 1}{2}  \\  \\ product \: of \: zeroes =  \frac{3}{2}  \times  - 2 \\  \\  =  - 3 \\  \\
