Answer 1

Respuesta:

El valor de P + Q es 2a²-6a-28

Explicación paso a paso:

Calcula P+Q si: P = (a + 5)(a - 2) Q = (a - 6)(a + 3)

Hallamos P:

P = (a+5)(a-2)

P = (a)(a) + (a)(-2) + (5)(a) + (5)(-2)

P = a²-2a+5a-10

P = a²-3a-10

Hallamos Q:

Q = (a-6)(a+3)

Q = (a)(a) + (a)(3) + (-6)(a) + (-6)(3)

Q = a²+3a-6a-18

Q = a²-3a-18

Calculamos P + Q:

P + Q = (a²-3a-10) + (a²-3a-18)

P + Q = a²-3a-10 + a²-3a-18

P + Q = a²+ a²-3a-3a-10-18

P + Q = 2a²-6a-28

Por lo tanto, el valor de P + Q es 2a²-6a-28
