Question

if a and b are two whole numbers, then which of a the following statement is not correct ? a+b=b+a 1 ab=ba 2 a-b =b-a​

Answer 1

Answer:

(x²+2x)(x+10)

(3x²+3x+4)(2x-1)

(2x+3)(3²-x-+1)

Step-by-step explanation:

Answer 2

Answer:

a-b ≠ b-a

Step-by-step explanation:

1)a+b=b+a

proof:2+3=3+2

5=5

2)ab=ba

proof:2×3=3×2

6=6

3)a-b=a-b

let's see,

2-3=3-2

-1=1

so,here we see is -1≠1(As one of the number contains -ve sign and another contains +ve sign).
