Question

Find two consecutive odd numberswhose product is 143

Answer 1

Let one odd no. = x
other consecutive odd no. = x+2

ATQ x(x+2) = 143
x^2 + 2x -143 =0
x^2 + 13 x- 11x -143 =0
x(x + 13) -11 ( x + 13) = 0
(x+13)(x-11)=0

so,the nos. are 11 and 13

Answer 2

the consecutive odd numbers are 11 and 13
