Question

Calcule o valor de k na equação
(k+5)*x2-10x +3=0
​

Answer 1

Resposta:

k=3

Explicação passo-a-passo:

(k+5)x²- 10x+3=0                      p= 3/8

p= c/a ------>   3/8 = 3/(k+5)

                       3(k+5)= 8*3

                       3k+15=24

                       3k=24-15

                       k=9/3

                       k=3

resposta: k= 3
