Question

The product of number and 2 more than that is 168, what are the number

Answer 1

Answer:

±12,14

Step-by-step explanation:

let numbers be x,x+2

(x)(x+2)=168

x²+2x=168

x²+2x-168=0

x²+14x-12x-168=0

x(x+14)-12(x+14)=0

(x-12)(x+14)=0

therefore,x=12,-14

case1:x=12

x+2=14

case 2:x= -14

x+2=-12
