Question

x²+19x+90=0 respuesta​

Answer 1

Respuesta:

X2 + 19 + 90 = 0

X2 + 109 = 0

X2 = 0 - 109

X2 = -109

X= -109 ÷ 2

X= -54.5

X2 + 9X + 8 = 0

11X + 8 = 0

11X = 0 - 8

11X = -8

X = -8 ÷ 11

X= -0.7272...

X2 + 19X + 90 = 0

21X + 90 = 0

21X = 0 - 90

21X = -90

X = -90 ÷ 21

X= -4.285714286

X2 + 7X + 42 = 0

9X + 42 = 0

9X = 0 - 42

9X = -42

X= -42 ÷ 9

X= -4.666667
