The coefficients are:
2
-5
1
Answer:
The solutions are 1 and 4
Step-by-step explanation:
Check the images
2n + 3 = 5
2n = 2
n = 1
the sum of 2 times a number and three means you add 2n + 3 and since it is equal to 5 you then solve for n.
Answer:
6 + 5x² - 2x + 3
Step-by-step explanation:
Given
( + 2x² - 4) - (-5 - 3x² + 2x - 7)
Remove the parenthesis on the first factor and distribute the second by - 1
= + 2x² - 4 + 5 + 3x² - 2x + 7 ← collect like terms
= 6 + 5x² - 2x + 3 ← in standard form
