How did he manage to give away more apples than he got?
ax²+bx+c=0Find the value of x.
ax² + bx + c = 0x² + bx/a + c/a = 0x² + bx/a = c/ax² + bx/a + b²/4a² = b²/4a² - c/a(x + b/2a)² = (b² - 4ac/4a²)x + b/2a = 1/2 sqrt((b² - 4ac/a²)) or x + b/2a = -(1/2) sqrt((b² - 4ac/a²))x = 1/2 sqrt((b² - 4ac/a2)) - b/2a or x + b/2a = -(1/2) sqrt((b² - 4ac/a²))x = 1/2 sqrt((b² - 4ac/a2)) - b/2a or x = - b/2a - 1/2 sqrt((b² - 4ac/a²))that's the farthest you can look into x
it's the quadratic formulai dont know why you got that but i used wolfram alpha :p
