Question

Fórmula De BhásKara
resolva:
x²+7+10 =0​

Answer 1

ײ+7×+10=0

∆=b²-4ac

∆=7²-4.1.10

∆=49-40

∆=9

×=-b±√∆/2a

×=-7±3/2

×'=-7+3/2=-4/2=-2

×"=-7-3/2=-10/2=-5

S={-2;-5}

Answer 2

∆=b²-4ac=7²-4.1.10=49-40=9 => √∆=3

x = -b±√∆/2a

x = -7±3/2.1

x' = -7+3/2= -4/2 = -2 ✓

x"= -7-3/2= -10/2 = -5 ✓

S: { -5 , -2} <=====©
