Answer:
Step-by-step explanation:
In this question, one is asked to multiply a fraction by a whole number, first model the question.
In a situation like this, one multiplies the whole number by the numerator (number) over the fraction.
Simplify,
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.
Answer:
Step-by-step explanation:
Biquadratic Equation
It's a fourth-degree equation where the terms of degree 1 and 3 are missing. It can be solved for the variable squared as if it was a second-degree equation, and then take the square root of the results
Our equation is
If we call , our equation becomes a second-degree equation
Dividing by -3
Factoring
It leads to these solutions
Taking back the change of variable, we have for the first solution
Now for the second solution, we get imaginary (complex) values
Summarizing, the four solutions for x are
