Question

Encontre as raizes da equacao do 2 grau x2 - 15x + 50=0 galera pfv preciso urgente

Answer 1

Delta = 15²-4.50.1
Delta = 225-200
Delta = 25
x = (15 +-√25)/2
x¹ = (15+5)/2 => (primeira raiz) x¹= 10
x² = (15-5)/2 => (segunda raiz) x² = 5

Answer 2

(-15)2-4.1.50
225-200
25
5
X1= -(-15)+5 x2= -(-15)-5
2 2
×1=20 x2=10
2 2
×1=10 x2=5
As raízes são {5, 10}
