6(-7 + 6i)(-4 + 2i)

6[(-7 + 6i)(-4 + 2i)]

6[-7(-4 + 2i) + 6i(-4 + 2i)]

6[-7(-4) - 7(2i) + 6i(-4) + 6i(2i)]

6(28 - 14i - 24i + 12i^2)

6(28 - 14i - 24i + 12(-1))

6(28 - 14i - 24i - 12)

6(16 - 38i)

6(16) + 6(-38i)

96 - 228i

-------------------------------------------------------

So, 6(-7 + 6i)(-4 + 2i) = 96 - 228i and it is in the form a+bi where a = 96 and b = -228
