Question

prove that 1*1=0
plzz prove

Answer 1

consider any two non zero no. let x and y be non zero no. such that
x=y
multiply both side by x
x²=xy
subtract y² from both sides
x²-y²=xy-y²
(x-y)(x+y)=y(x-y)
x+y=y. as we let x=y
y+y=y
2y=y
2=1
subtract 1 from both sides
2-1=1-1
1=0
multiply both side by 1
1*1=0*1
1*1=0

Answer 2

Answer:

mark me

Step-by-step explanation:

onsider any two non zero no. let x and y be non zero no. such that

x=y

multiply both side by x

x²=xy

subtract y² from both sides

x²-y²=xy-y²

(x-y)(x+y)=y(x-y)

x+y=y. as we let x=y

y+y=y

2y=y

2=1

subtract 1 from both sides

2-1=1-1

1=0

multiply both side by 1

1*1=0*1
