Question

resolva a equacao na formula de bhaskara : x²+12x+36=0

Answer 1

Vamos lá :

x² + 12x + 36 = 0

a = 1 ; b = 12 ; c = 36

Δ = b² - 4ac
Δ = 12² - 4.1.36
Δ = 144 - 144
Δ = 0      ----> √Δ = 0

Utiliza a formula de Bhaskara ..

x = - b +/- √Δ / 2a
x = - 12 +/- 0 / 2.1
x = - 12 +/- 0 / 2

x' = - 12 + 0 / 2   ⇒  x' = - 12 / 2   ⇒ x' = - 6
x'' = - 12 - 0 / 2   ⇒  x'' = - 12 / 2  ⇒ x'' = - 6

S = {- 6}

Espero ter ajudado !!!
