Use the FOIL method: First, Outside, Inside, Last
3x(2x) = 6x²
3x(-4) = -12x
3(2x) = 6x
3(-4) = -12
6x² -12x + 6x-12
Combine like terms
-12x + 6x = -6x
6x² - 6x - 12 is your answer
hope this helps
The answer would be 9a^2-4
Answer:
<h2>The rational root of the given polynomial is 42.59.</h2>
Step-by-step explanation:
The polynomial is given by 2x + 5.82 - 81 - 10 = 0
or, 2x + 5.82 - 91 = 0
or, 2x = 85.18
or, x = 42.59.
The rational roots of any polynomial = the ratio of the factors of constants and factors of leading coefficients.
