The quadratic equations are solved and answered below -
<h3>What is a equation?</h3>
An equation is a mathematical statement showing the equivalence of two mathematical expressions. Example -
3x + 5 = 8
Given is -
3x² - 7 = 31
2x² + 18 = 0
4x² - 26 = - 50
2x² + 36 = x²
We have -
3x² - 7 = 31
3x² = 38
x² = 38/3
x² = 12.67
x = ±3.56
2x² + 18 = 0
2x² = - 18
x² = -9
x = ±3i
4x² - 26 = - 50
4x² = - 24
x² = -6
x = ±√6i
2x² + 36 = x²
x² = - 36
x = ±√6 i
Therefore, the quadratic equations are solved above.

Hi! So basically what you'll be doing is multiplying the exponents together :))
So It'd be 3x5 which is 15 so it'd be 10 to the power of 15.
Hope I helped :)) and ask more if you need help

sorry if I'm wrong
Answer:
Point S represent the score 93.5 which is Drew's New Score.
Step-by-step explanation:
The score of Drew on a math test = 92
Point for each correction in the math test = 1/2 = 0.5
Now, the number of problems corrected = 3 x 0.5 = 1.5
So, Now, the new scale of Drew = Old Score + The Correction Score
= 92 + 1.5
= 93.5
or, Drew, new score = 93.5
Hence, point S represent the score 93.5 which is Drew's New Score.
