6 is in the tenths place, 8 is in the hundredths place, and 2 is in the thousandths place. Since 8 is greater than 5, you round the 6 up to 7.
Answer:
it looks good!
Step-by-step explanation:
Answer:
2x² + 5x - 3
Step-by-step explanation:
(x + 3)(2x - 1)
Use FOIL
First terms
x * 2x = 2x²
Outer terms
x * -1 = -x
Inner terms
3 * 2x = 6x
Last terms
3 * -1 = -3
---------------------
FOIL
2x² - x + 6x - 3
Combine like terms
2x² + 5x - 3
