What are all of the real roots of the following polynomial? f(x) x^4-24x^2-25

Greeley [361]

Answer:

x = ±5

Step-by-step explanation:

We are given the following polynomial function and we are to find all of its real roots:

$x^4-24x^2-25$

Let $y=x^2$ so we can now write it as:

$y^2-24y-25$

Factorizing it to get:

$(y^2+y)+(-25y-25)$

$y\left(y+1\right)-25\left(y+1\right)$

$\left ( y + 1 \right ) \left ( y - 2 5 \right)$

Substitute back $y=x^2$ to get:

$\left ( x^2 + 1 \right ) \left ( x^2 - 25 \right )$

$\left ( x^2 + 1 \right ) \left ( x + 5 \right ) \left ( x - 5 \right )$

The quadratic factor has only complex roots. Therefore, the real roots are x = ±5.

Find the value if x and if nessesary express your answer as a simplified radical

tekilochka [14]

Answer:

10 rad 3 / 2

Step-by-step explanation:

x = missing angle of the full traingle

180 - (90 + 60) = x

180 - 150 = x

30 = x

10 rad 3 / 2 = x

this is just my understanding of the problem- im sorry if im incorrect

Can yah help me with those two question please :(

Maurinko [17]

Solution 1 :-

Statement : corresponding angles in similar triangles must be congruent .

Answer : True

Solution 2 :-

Statement : The hypotenuse of a right angle triangle has to be opposite of 90 degree .

Answer : True

Reason : We know that the side opposite to largest angle in a triangle is largest . Since in a right angle triangle 90 degree is the largest angle and hypotenuse is the longest side therefore they must be opposite to each other .
