Answer: n=3
Step-by-step explanation:
6n-10=8
6n=18
n=3
You start by adding 10 to both sides and then divide both sides by 6.
13+8n=-3
<em>Subtract 13 from both sides</em>
8n=-16
<em>Divide both sides by 8</em>
n=-2
A,b,c, d that’s the answer
T to the 4th power then multiply by 3.
2x^2 + x + 3=0 has only complex roots.
The determinant is 1-4*2*3 = -23
-23 (or any determinant) is the part under the square root sign, If that determinant is negative, knowing you cannot take the square root of a negative number, we know the answers must be complex.
