Find the solution by grouping

Mathematics
1 answer:
Karolina [17]3 years ago
7 0

Answer:

Step-by-step explanation:

x^{5} -x^{4}-2x^{3}  +2x^{2} =0\\\\x^{4} (x-1) -2x^{2} (x-1) =0\\\\(x^{4} -2x^{2} ) (x-1)=0\\\\ x^{2} (x^{2} -2)(x-1) =0

solutions are

x² =0 so x=0

x²-2 = 0 so x= ±√2

x-1 =0 so x= 1

According to the rational root theron what are all the potential roots of f(x)=9x^4-2x^2-3x+4
Viefleur [7K]

Answer:

<u>Potential roots:</u>  \frac{9}{4},\frac{9}{2},9,\frac{3}{4},\frac{3}{2},3, \frac{1}{4},\frac{1}{2},1

Step-by-step explanation:

Simply put, the rational roots theorem tells us that if there are any rational roots of a polynomial function, they must be in the form

±  \frac{FactorsOfa_{0}}{FactorsOfa_n}

Where

a_n is the number before the highest power of the polynomial, and

a_0 is the constant in the polynomial

<em>From the polynomial shown, we have a_n = 9 and a_0 = 4</em>

<em />

<em>The factors of 9 are 9, 3, 1</em>

<em>and</em>

<em>The factors of 4 are 4,2,1</em>

<em />

So, if there are any rational roots, they would be:

±  \frac{FactorsOfa_{0}}{FactorsOfa_n}

±  \frac{9,3,1}{4,2,1}

Which is  ±   9/4, 9/2, 9/1, 3/4, 3/2, 3/1, 1/4, 1/2, 1/1

or

\frac{9}{4},\frac{9}{2},9,\frac{3}{4},\frac{3}{2},3, \frac{1}{4},\frac{1}{2},1

Angel says that raising fraction to the power of -1 is the same as finding the reciprocal of the fraction do you agree
Dovator [93]

Answer:

yes, because when you "raise a number to power" you're multiplying the number by itself, and the power represents how many times you do so.

I hope this answers your question
