Answer:
The answer would be A/B=H
Step-by-step explanation:
To get rid of the B that is connected to the H, you would do the opposite of what they used. Meaning since the two were multiplied you would divide them. So, you would take your b and divide it on both sides of the equal sign. B and B cancels each other out so you are left with A/B which equals H.
Answer:
a = 0,-1
Step-by-step explanation:
a^2 + a=0
Factor out an a
a(a+1) =0
Using the zero product property
a=0 a+1 =0
a=0 a= -1
Answer:
Step-by-step explanation:
For #2, remember that 
, so 
Also, (a+b)(a-b), where a and b are any numbers, (a+b)(a-b)=
. Now, to simplify, or radicalize, a number with surds in the denominator, you have to multiply the denominator by its conjugate. If there is a complex number 
, where a and b are any numbers, the conjugate is always 
. Lets apply these rules. The conjugate of 4+6i is 4-6i, so do this:
Our answer is (28-3i)/(26)!
