Factorize the following expression ab-a-b+1
dolphi86 [110]

Group 'em together

a b − a + 1 − b

a b − a = a ( b − 1 )

Notice that there will be a 1 as without it it'll simply be  ab

1 − b = 1 ( 1 − b )

Notice that it doesn't match with the upper one... so we'll change the signs

1 ( 1 − b ) = − 1 ( b− 1 )

(try to multiply them now!!

Jot them down in one expression

a ( b − 1 ) − 1 ( b − 1 )

You get!!!!!!

( a − 1 ) ( b − 1 )

Adam’s father is 3 times as old as Adam. Two years ago, Adam was 15 years old. How old will his father be in 5 years?
Nata [24]

Answer: 56 years

Step-by-step explanation:

Let Adam's age be x , since the father is 3 times as old as him , then the father will be 3x.

Two years ago

Adam = x - 2

Father = 3x - 2

since Adam was 15 years old 2 years ago , this means that

x-2=15

add 2 to both sides

x = 17

Therefore , Adam is presently 17 years old , then the father will be 3(17) years , which means that the father is presently 51 years old.

In 5 years time , the father will be 51 + 5 years old. That is , the father will be 56 years old in 5 years time
