Question

The house number of reemais 3 less than seema if the product of their house number is 88 what are the house number

Answer 1

let seema's house no. be x.

so reema's house no. will be x-3.

x(x-3)=88.

= x²-3x =88

= x²-3x-88=0

= x²+8x-11x-88=0

= x(x+8)-11(x+8)=0

x-11=0, x=11.

x+8=0,x=-8

since x can't be -ve. x=11.

so seema's house no. is 11 and seema's house no. is 11-3 =8.

Answer 2

let seema's house no. be x.

so reema's house no. will be x-3.

x(x-3)=88.

= x²-3x =88

= x²-3x-88=0

= x²+8x-11x-88=0

= x(x+8)-11(x+8)=0

x-11=0, x=11.

x+8=0,x=-8

since x can't be -ve. x=11.

so seema's house no. is 11 and seema's house no. is 11-3 =8.
