Question

Dado los polinomios A(t), B(t)donde: A(t) =3t²- 5t + 6 y B(t) = t² + t - 10
Hallar el valor de C (t) Cuando t = -2. Sabiendo que C (t) = A(t) + B(t)
A)20
B)29
C)35
D)45

Answer 1

C (t) = A(t) + B(t)
C (t) = 3t²- 5t + 6 + t² + t - 10
C (t) = 4t² - 4t -4
C(-2) = 4(-2)² - 4(-2) -4
C(-2) = 20

Answer 2

C(t) = A(t) + B(t) = 3t²- 5t + 6+t² + t - 10 = 4t²- 4t - 4
C(t) = 4t²- 4t - 4
C(-2) = 4(-2)²-4(-2)-4 = 20

Respuesta C(-2) = 20, (literal A).
