Question

445×555 evaluate using identity​

Answer 1

Answer:

Correct option is A)

Divisor =555+445=1000

Quotient =2×(555−445)=220

Remainder =30

∴ Dividend=Divisor×Quotient+Remainder

=1000×220+30=220030

Answer 2

Answer:

by using 4th identity we get

(x+a)(x+b)=x²+(a+b)x+ab

445×555=(500+(-55))(500+55)

=500²(-55+55)500+(-55)×55

=250000+(0)500+(-3025)

=250000+(-3025)

=250000-3025

=246975
