Question

How do you multiply 3 binomials?

Answer 1

multiply two of then to get a trinomial, then multiply the trinomial times the remaining binomial.

Answer 2

By taking the example of

(x+a)(x+b)(x+c)

First multiply the first two binomials

=(x+a)(x+b)

=x(x+b)+a(x+b)

=x^2 + bx + ax + ab

then by taking the result multiply by third binomial

=(x^2+bx+ax+ab)(x+c)

=x(x^2+bx+ax+ab)+c(x^2+bx+ax+ab)

=x^3+bx^2+ax^2+abx+x^2c+bxc+axc+abc

I hope this would help you a lot

note:^2 means the square and ^3 means the cube of a number
