Kinda struggling need find the answer x^2+6x-72=0

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

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
