<u><em>Answer:</em></u>
D. 60
<u><em>Explanation:</em></u>
<u>The general form of the quadratic equation is:</u>
ax² + bx + c = 0
<u>The given equation is:</u>
3x² + 6x = 2
This can be rewritten as:
3x² + 6x - 2 = 0
<u>By comparison, we can find that:</u>
a = 3
b = 6
c = -2
<u>Now, the discriminant of a quadratic equation is given by:</u>
b² - 4ac
<u>Substitute with the given values to get the discriminant for the given equation as follows:</u>
b² - 4ac = (6)² - 4(3)(-2)
= 36 - (-24)
= 36 + 24
= 60
Hope this helps :)
Answer:
15
^2
−
2
3
Step-by-step explanation:
The answer is 3 + √5 and 3 - √5.
This is quadratic equation: x²
- 6x +
4 = 0
The general quadratic equation is ax² +
bx +
c = 0
Our equation can be rewritten: 1x² + (-6)x + 4 = 0
So, in our equation we have: a = 1, b = -6, c = 4
Now, x can be calculated using the formula:


From here:
It is a 5% discount 400 x .05 = 20
400 - 20 = 380
The value of the x if e3*6 - 87 equals e3x - 81
