(hope this helps can i plz have brainlist :D hehe)
Step-by-step explanation:
Express each of the following in a+bi form. a)(2 +5i)+(4 +3i)b)(−1+2i) − (4 − 3i)c)(5+3i)(3 +5i)d)(1 +i)(2 − 3i) +3i(1− i) − i
1 answer:
Answer:
a 6+ 8i
b -5 + 5i
c 34i
d 8 + i
Step-by-step explanation:
<h3>a)(2 +5i)+(4 +3i)</h3><em>Add them together </em>6 + 8i
<h3>b)(−1+2i) − (4 − 3i)</h3><em>Add them together </em>-5 + 5i
<h3>c)(5+3i)(3 +5i)</h3><em>Multiply it out</em> 15 + 25i + 9i + 15
<em>Add them together ( = the number times -1) </em> 34i
<em>Multiply it out</em> (2 - 3i + 2i - 3) + (3i - 3
) - i
<em>Add what is in the parenthesis together ( = the number times -1) </em>(5 - i) + (3 + 3i) - i
<em>Add them together </em>8 + i

Answer:
Step-by-step explanation:
We have been given a function . We are asked to find the zeros of our given function.
To find the zeros of our given function, we will equate our given function by 0 as shown below:
Now, we will factor our equation. We can see that all terms of our equation a common factor that is .
Upon factoring out , we will get:
Now, we will split the middle term of our equation into parts, whose sum is and whose product is
. We know such two numbers are
.
Now, we will use zero product property to find the zeros of our given function.
Therefore, the zeros of our given function are .
