simplify 7i\times 3i(-8-6i)

simplify

7 i \cdot 3 i (- 8 - 6 i)

168 + 126 i

Solution steps

7 i 3 i (- 8 - 6 i)

Simplify

7 i 3 i (- 8 - 6 i) : 21 i^{2} (- 8 - 6 i)

= 21 i^{2} (- 8 - 6 i)

Apply the distributive law:

a (b - c) = ab - a c

21 i^{2} (- 8 - 6 i) = 21 i^{2} (- 8) - 21 i^{2} \cdot 6 i

= 21 i^{2} (- 8) - 21 i^{2} \cdot 6 i

Simplify

21 i^{2} (- 8) - 21 i^{2} \cdot 6 i : 168 + 126 i

= 168 + 126 i
