Step-by-step explanation:
ax2 + bx + c = 0
x12 = (-b ± √D) / 2a , D = b2 - 4ac .
5x2 + 7x + 3 = 0
a = 5 , b = 7 , c = 3
D = 49 - 60 = - 11 , x1 = (-7 - i √11) / 10
x2 = (-7 + i √11) / 10
Answer:
5+n
you have to distribute the “+” so you can drop the parenthesis. Then, you have 3+2+n. Add and you end up with 5+n
The answer is 0.3.
Take for instance, a numberline. The positive numbers are always greater than the negative numbers. Even though you have this type of question:
Which number is greater +100,000 or -100,000?
The answer would still be 100,000 because any positive number is always greater
