2x² + 3x -8 = 0
a = 2 , b = 3 , c = -8
So..
D = b²-4ac = 9 + 64 = 73
for bigger solution , use x = -b + √D / 2a
For smaller solution, use x = -b - √D / 2a
So
= -3 + √73 / 2. 2
= 1/4 (√73 -3)
Hopefully helpfull.. ^_^
Answer:
C
Step-by-step explanation:
Its giving you extra info to confuse you but the longest movie is 3 hours and shortest is 1. So 3-1=2
So it would be C
Answer: It’s A
Step-by-step explanation: C= -14/3 which is simplified to -4 2/3
The answer is B
2x - 7 when x = 5
2x - 7
2(5) - 7
10 - 7
3
3 is a prime number because it has only two distinct divisors: 1 and itself (3)
