10) x^2y-5xy-2x+11y

Step-by-step explanation:

i did not check my work

x = {-12, 6}

Step-by-step explanation:

Need to find two numbers whose product equals the c-value of -72 and sum equals the b-value of +6.

x² + 6x - 72 = 0

              ∧

           -1  +72 = 71

          -2  +36 = 34

         -3   +24 = 21

         -4   +18 = 14

         -6   +12 = 6   -->  this works!  

(x - 6)(x + 12) = 0

x - 6 = 0    and     x + 12 = 0

    x = 6    and           x = -12
