Question

determine os valores de aeb para que sejam iguais os polinomios p(x) =3x+2 e 9(x)=(a+b)x+(a+3)x+(2-b
)

Answer 1

 p(x) =3x+2 e 9(x)=(a+b)x+(a+3)x+(2-b)

 3x+2 =(a+b)x+(a+3)x+(2-b)

3 = a+b+a+3 ==> 3 = 2a + b + 3 ==> 2a + b = 3-3 ==> 2a + b = 0

2a + 0 = 0 ==> 2a = 0 ==> a = 0

2 = 2 - b ==> b = 2-2 ==> b = 0

a e b = 0
