3 x²-4xy+y²=0 factorize<br>​
Igoryamba

The factorization will be (x-y)*(3x-y) .

Factorization : Factorization is a method of breaking the arithmetic algebraic expressions into the product of their factors. If we multiply the factors again, then they will result in original expression. The given question is a quadratic equation . Therefore we'll get two parts on breaking and 2 roots .

Factorizing : 3 x²-4xy+y²

Splitting term -4xy into - 3xy and -xy

3x^{2} - 3xy -xy + y^{2}

Taking common from first two and last two terms ,

3x (x-y) + y(-x+y)

Taking minus common from last term ,

3x(x-y) - y(x-y)

Again taking common

(x-y) * (3x-y)

Hence , the factorization will be  3 x²-4xy+y² = (x-y) * (3x-y) .

Complete question:

Para ingresar a la Universidad del Chocó se aplica una prueba de razonamiento que consta de 30 preguntas. Por cada respuesta correcta se asignan 5 puntos y por cada incorrecta (o no contestada) se restan 2 puntos. Si un participante obtuvo un puntaje de 94 puntos, ¿cuantas preguntas respondió bien?

Responder:

número de respuestas correctas = 22

Explicación paso a paso:

Dado lo siguiente:

Número total de preguntas = 30

Deje respuestas correctas = y; Respuestas incorrectas = n

Marca otorgada por y = 5

Marca deducida por n = 2

Si el total de preguntas = 30; luego

y + n = 30 - - - - (1)

Puntuación total obtenida = 94; luego

5y - 2n = 94 - - - (2)

De 1),

y + n = 30

y = 30 - n

Sustituya y = 30 - n en equ (2)

5 (30 - n) - 2n = 94

150 - 5n - 2n = 94

150 - 7n = 94

-7n = 94-150

-7n = - 56

n = 56/7

n = 8

Sustituir n = 8 en (1)

y + n = 30

y + 8 = 30

y = 30 - 8

y = 22

y = número de respuestas correctas = 22

n = número de respuestas incorrectas = 8
