Question

augem pode me ajudar com a fórmula de Bhaskara x²-8x+15=0​

Answer 1

x2 - 8x + 15 = 0

∆ = ( 8 ) 2 - 4• 1 • 15

∆ = 64 - 60

∆ = 4

X1 = ( 8 + √4 ) / 2

X1 =( 8 + 2 ) / 2

X1 = 10 /2

X1 = 5

X2 = ( 8 - √4 ) / 2

X2 = ( 8 - 2 ) / 2

X2 = 6 / 2

X2 = 3

Answer 2

️= b2 -4xaxc

️= (8)2 -4x1x15

️= 64 - 60

️= 4

X= -b+/- V4

2xa

X= -8 +/- 2

X'= -8 + 2 = -6 = -3

X'' = -8 - 2 = -10 = -5
