Question

Two positive, consecutive, odd integers have a product of 143.

Complete the equation to represent finding x, the greater integer.

x(x –
) = 143



What is the greater integer?

Answer 1

Explanation:

x and x+2 are the numbers

x(x+2)=143

x²+2x-143=0

x²+13x-11x-143=0

x(x+13)- 11(x+13)=0

(x+13). (x-11)=0

x+13=0. x=-13

x-11=0. x=11
