When asked to factor the x^2-121 a student gives the answer (x-11)(x-11) what is wron with this answer?

Art [367]

Given expression is x² - 121

This is called Difference of Squared terms, we have a formula that is given as :-

a² - b² = (a - b) · (a + b)

Now using the above formula in the given expression, we get :-

x² - 121

x² - (11)²

here a = x and b = 11

x² - (11)² = (x - 11) · (x + 11)

but it says that student gave the answer as (x - 11) · (x - 11).

So, student's answer should be (x - 11) · (x + 11) instead of product of two (x - 11) terms.

What is the value of (3/10)3

Elenna [48]

Answer:

$\frac{9}{10}$

Step-by-step explanation:

In this question, one is asked to multiply a fraction by a whole number, first model the question.

$\frac{3}{10}(3)$

In a situation like this, one multiplies the whole number by the numerator (number) over the fraction.

$\frac{3*3}{10}$

Simplify,

$\frac{9}{10}$

A common error that people make is that they will multiply both the numerator and denominator by the whole number, this is the same as multiplying the answer by (1), thus it is incorrect.
