Question

write a pair of integers whose product is -36 and whose difference is 15​

Answer 1

Step-by-step explanation:

let the 2 no. be x and y

such that x*y= -36 and x-y = 15

x= 15+y........(1)

substitute (1) in x*y

(15+y)y=-36

15y+y² = -36

y²+15y+36 = 0

y²+12y+3y+36=0

y(y+12)+3(y+12)=0

(y+3)(y+12)=0

y=-3 y=-12

x = 15+(-3) x = 15+(-12)

x = 15-3 x = 15-12

x = 18 x = 3
