Show all work to factor x^4 − 5x^2 + 4 completely.
Mademuasel [1]

Answer:

(x+1) (x-1) (x+2) (x-2)

Step-by-step explanation:

<u>Let u = x^2</u>

= u^2 - 5u + 4

<u>(Factor u^2 - 5u + 4)</u>

= (u-1) (u-4)

<u>Substitute back u = x^2</u>

= (x^2 -1 ) (x^2 - 4)

<u>Factor x^2 - 1 and x^2 -4</u>

= (x+1) (x-1) (x+2) (x-2)

Hope this helped... :)

What is the ratio of the area of the inner square to the area of the outer square?
Anastasy [175]

Answer:

\frac{(a-b)^2+b^2}{a^2}

Step-by-step explanation:

Since, By the given diagram,

The side of the inner square = Distance between the points (0,b) and (a-b,0)

=\sqrt{(a-b-0)^2+(0-b)^2}

=\sqrt{(a-b)^2+b^2}

Thus the area of the inner square = (side)²

=(\sqrt{(a-b)^2+b^2})^2

=(a-b)^2+b^2\text{ square cm}

Now, the side of the outer square = Distance between the points (0,0) and (a,0),

=\sqrt{(a-0)^2+0^2}

=\sqrt{a^2}=a

Thus, the area of the outer square = (side)²

=a^2\text{ square cm}

Hence, the ratio of the area of the inner square to the area of the outer square

=\frac{(a-b)^2+b^2}{a^2}
