Question

Como sacar el resultado de estas operaciones usando la fórmula general

Answer 1

Explicación paso a paso:

• x² + 11x + 24 = 0

A = 1 ; B = 11 ; C = 24

• –11 +/- ✔11² – 4 × 1 ×24 / 2 × 1
• –11 +/- ✔121 – 96 / 2
• –11 +/- ✔ 25 / 2
• –11 +/- 5 / 2

X1 = –11 + 5 / 2

X1 = – 6 / 2

X1 = –3

X2 = –11 – 5 / 2

X2 = –16 / 2

X2 = –8

• 6x² – x – 222 = 0

A = 6 ; B = –1 ; C = –222

• –(–1) +/- ✔(–1)² – 4 × 6 × – 222 / 2 × 6
• 1 +/- ✔ 5329 / 12
• 1 +/- 73 / 12

X1 = 1 + 73 / 12

X1 = 74 / 12

X1 = 37 / 6

X2 = 1 – 73 / 12

X2 = – 72 / 12

X2 = –6

• x² + 4x + 3 = 0

A = 1 ; B = 4 ; C = 3

• –4 +/- ✔4² – 4 × 1 × 3 / 2 × 1
• –4 +/- ✔16 – 12 / 2
• –4 +/- ✔4 / 2
• –4 +/- 2 / 2

X1 = –4 + 2 / 2

X1 = –2 / 2

X1 = –1

X2 = –4 – 2 / 2

X2 = – 6 / 2

X2 = – 3
