Answer:
1) -15+8i
2) x^2+2x-5
Step-by-step explanation:
1) apply perfect square formula
(4i)^2+2*4i1+1^2
then simplify
2)remove parentheses
x+1+(x-2)(x+3)
expand (x-2)(x+3)
x+1+x^2+x-6
simplify x+1+x^2-6 = x^2+2x-5
Hey, I am able to help you today :)
Step 1 - Simplify:
420x^2 - 18 = 2082
Step 2 - Add 18 to both sides:
420x^2 = 2082 + 18
Step 3 - Simplify 2082 + 18 to 2100:
420x^2 = 2100
Step 4 - Divide both sides by 420:
x^2 = 2100/420
Step 5 - Simplify 2100/420 to 5
x^2 = 5
Step 6 - Simplify:
x = 5
Step 7 - Check your answer:
10 x 42 x 5 - 18 =2082
Hope this helps you today :)
Step-by-step explanation:

Let the number of panels Plant B produced be x.
The power of products property states that for number
enclosed in a bracket or parenthesis, if it is raised to a power, it must be
multiplied to the power of the enclosed number no matter how different the base
is. You cannot add it because it is not raised. You can only add it if they
have the same base. But in this problem, you will just multiply it. The breakdown
of the solution to this problem is shown below. So,

= 6x15y6</span><span>
