Slove for pls quick

5x^2 - 2x + 5 = 0

Let's solve your equation step-by-step.

5x2−2x+5=0

Step 1: Use quadratic formula with a=5, b=-2, c=5.

x=

−b±√b2−4ac

2a

x=

−(−2)±√(−2)2−4(5)(5)

2(5)

x=

2±√−96

10

No real solutions.

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
