Question

Multiply: -2 x - 1x-1 x -3x -8 X 0​

Answer 1

Step-by-step explanation:

Cross multiply the terms,

(

x

−

2

)

2

=

(

x

+

1

)

2

|

x

−

2

|

=

|

x

+

1

|

If both x-2 and x+1 are positive or negative, then this has no solution.

If x+1 is negative, then x-2 is also negative. (

x

+

1

<

0

means

x

<

−

1

which means maximum value of

x

−

2

is less than

−

1

−

2

=

−

3

which is also negative)

So our only option is if x-2 is negative and x+1 is positive.

In this case,

|

x

−

2

|

=

2

−

x

and

|

x

+

1

|

=

x

+

1

We have,

2

−

x

=

x

+

1

2

x

=

1

x

=

1

Answer 2

first we will multiply

-2×-1=+2

then

+2×-1=-2

then

-2×-3=+6

then

+6×-8=-48

then

-48×0=0

0 is the answer
