PRACTICA N1 ALGEBRA

Factorizar la siguiente expresión : P(x) = 6x² – x – 2

¨Indica la suma de factores primos.¨

• 5x+1

• 5x-1

• 6x-8

• x-1

Factoriza: P(x) = x² – 3x – 40 e indica el factor primo con mayor término independiente

• x+5

• 12x-9

• x-8

• 2x-3

Factoriza: P(x) = x² + 8x + 15

• (x + 5)(x + 3)

• (x + 8)(x + 1)

• (x + 7)(x - 3)

• (x + 9)(x + 3)

Factoriza: P(x) = x² – 5x – 24

• (x – 1)(x – 4)

• (x – 8)(x + 3)

• (x – 6)(x + 1)

• (x + 3)(x + 8)

Resuelve: x² – 3x – 18 = 0

• (x-6)(x+3)

• (x-8)(x+9)

• (x-9)(x+2)

• (x-1)(x+3)

Resuelve: x² – 49 = 0

• {–7; 7}

• {–5; 5}

• {–8; 8}

• {–3; 3}

Resuelve: x² – 3x – 7 = 0
