2x(3a-2x) + a(2x-a)-3x(a+x)

x = 1/14 i sqrt(3) a + (5 a)/14 or x = -1/14 i sqrt(3) a + (5 a)/14

Step-by-step explanation:

Solve for x:

-a^2 + 5 a x - 7 x^2 = 0

Divide both sides by -7:

a^2/7 - (5 a x)/7 + x^2 = 0

Subtract a^2/7 from both sides:

x^2 - (5 a x)/7 = -a^2/7

Add (25 a^2)/196 to both sides:

(25 a^2)/196 - (5 a x)/7 + x^2 = -(3 a^2)/196

Write the both sides as a square:

(x - (5 a)/14)^2 = -(3 a^2)/196

Take the square root of both sides:

x - (5 a)/14 = 1/14 i sqrt(3) a or x - (5 a)/14 = -1/14 i sqrt(3) a

Add (5 a)/14 to both sides:

x = 1/14 i sqrt(3) a + (5 a)/14 or x - (5 a)/14 = -1/14 i sqrt(3) a

Add (5 a)/14 to both sides:

x = 1/14 i sqrt(3) a + (5 a)/14 or x = -1/14 i sqrt(3) a + (5 a)/14

i would pic false cause it goes down towards negative
