Question

f(x) = -10x + 24 + x² Determine as raízes da função POR FAVOR AJUDEEEEM!!!!!

Answer 1

f(x) = -10x + 24 + x²

-10x + 24 + x² = 0

Δ = (-10)² - 4 · 1 · 24

Δ = 100 - 96

Δ = 4

$x_1 = \frac{-(-10) - \sqrt{4} }{2*1} = \frac{10-2}{2} = \frac{8}{2} = 4\\\\ x_2 = \frac{-(-10) + \sqrt{4} }{2*1} = \frac{10+2}{2} = \frac{12}{2} = 6$
