1 answer:

6 0

Here you need to apply the complex arithmetic rule: (a+bi) (c+di)
a=-1
c=-8
b=8
d=8
(-1 · (-8) -8·8) + (-1 · 8i+8(-8)i
8-64+-8i-8i-64i
-56-72i

Algebra 2<br>how to simplify 2{4x-3(x+5)+10}+3(x-2)

algol13

Question: 2{4x - 3(x + 5) + 10} + 3(x - 2)

Steps

1. Expand 4x - 3(x + 5) + 10 = x - 5

= 2(x - 5) + 3(x - 2)

2. Expand 2(x - 5) = 2x - 10

= 2x - 10 + 3(x - 2)

3. Expand 3(x - 2) = 3x - 6

= 2x - 10 + 3x - 6

4. Then, simplify:

Add 2x + 3x = 5x

Add -10 - 6 = -16

5. Plug it in:

5x - 16 <-------------- Answer
