Evaluate the expression (-4+4i)(1+4i)(1+4i) and write the result in the form a+bi

Step-by-step explanation:

Since 2 of the 3 binomials are identical I would start the distribution there.

(1 + 4i)(1 + 4i) =

I'm sure you have learned in class by now that i-squared is = to -1, so we can make that substitution:

1 + 8i + 16(-1) which simpifies to

1 + 8i - 16 which simplifies further to

-15 + 8i.  Now we need to FOIL in the last binomial:

(-15 + 8i)(-4 + 4i) =

Combine like terms to get

Again make the substitution of i-squared = -1:

60 - 92i + 32(-1) which simplifies to

60 - 92i - 32 which simpifies, finally, to a solution of:

28 - 92i

your answer is the frist one

hop i

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
