Answer:

I hope this would help you!!!

Step-by-step explanation:

=297 * 303.

= (300-3)(300+3 )

since (x+a)(x+b)= x^2 + (a+b)x + ab

here x = 300 , a= -3 , b = +3

baby substituting in the formula we get,

[300 + (-3)] [300+3] = (300)^2 +(-3+3)300+(-3)(3)

= 90000 + (0)300 + (-9)

= 90000+0 -9

= 90000 - 9

= 89991
