Write the result of (4+9i)(7-4i) in a+bi form

Serhud [2]

ANSWER

$(4 + 9i)(7 - 4i) = 64 + 47i$

EXPLANATION

The given complex number expression is:

$(4 + 9i)(7 - 4i)$

We expand using the distributive property to get;

$(4 + 9i)(7 - 4i) = 4(7 - 4i) + 9i(7 - 4i)$

$(4 + 9i)(7 - 4i) = 28- 16i + 63i - 36 {i}^{2}$

Recall that,

${i}^{2} = - 1$

Our expression now simplifies to:

$(4 + 9i)(7 - 4i) = 28 + 47i + 36$

$(4 + 9i)(7 - 4i) = 64 + 47i$
