Question

2 consecutive nos whose product is 60
pls answer fast​

Answer 1

$\bold \red{answer}$

Let the two numbers be x & y

Given: xy = 60

x+y = -19

( x + y )^2 = -19^2 = 261

( x - y )^2 = ( x + y )^2 - 4xy

( x - y ) ^2 = 261- 4×60 = 121

x - y = √121 = + 11 or -11

x + y= -19

If x- y is +11

x - y = +11

Answer: 2x = - 8, x = -4 & y = -15

If x - y = -11

Answer: 2x = -30, x = -15 and y = -4
