Which of these is a correct expansion of (3x – 2)(2x2 + 5)? A.3x • 2x2 + 3x • 5 + (–2) • 2x2 + (–2) • 5

B.3x • 2x2 + 3x • 5 + 2 • 2x2 + 2 • 5

C.3x • 2x2 + (–2) • 2x2 + 2x2 • 5 + (–2) • 5

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
