Question

Starting from (-2) x 3, write the different products depicting definite patterns to verify that (-2) x (-2) = 4.

Answer 1

Answer:

-2 *3

Step-by-step explanation:

-2* we can write 3 like this

-2x-2(-1)

multiple this

we can get

-2x-2= 4

hence proved

Answer 2

Given :  (-2) ×3,

To Find :  use definite patterns to verify that (-2) ×(-2) =4.​

Solution:

(-2) ×3 = 6

(-2) × 2 = - 4    ( - 6 + 2 = - 4)

(-2) × 1 =  -2   (-4 + 2 = - 2)

(-2) × 0  = 0   (-2 + 2 = 0)

(-2) × (-1 )=  2   ( 0 + 2 = 2)

(-2) × (-2)  = 4   ( 2 + 2 = 4)

Value is increasing by 2  when factor multiplied by -2 is reducing by 1
