2ab^2 + (-5ab^2) = 2ab^2 - 5ab^2 = -3ab^2
-6ab^2 + 3ab^2 = -3ab^2
answer is 3ab^2

Answer:
The irrational conjugate theorem states that if a polynomial equation has a root (a + √b), then we can say that the conjugate of (a + √b), i.e. (a - √b) will also be another root of the polynomial.
Step-by-step explanation:
The irrational conjugate theorem states that if a polynomial equation has a root (a + √b), then we can say that the conjugate of (a + √b), i.e. (a - √b) will also be another root of the polynomial.
For example, if we consider a quadratic equation x² + 6x + 1 = 0, then two of its roots are - 3 + √8 and - 3 - √8 and they are conjugate of each other. (Answer)
Answer:
403.33 kilometros
Step-by-step explanation:
De la pregunta anterior:
6 litros = 110 kilómetros
22 litros = x
Cruz multiplicar
6 litros × x = 22 litros × 110 kilómetros
x = 22 litros × 110 kilómetros / 6 litros
x = 403.33 kilometros
Así, 22 litros recorrerán 403.33 kilómetros
