X^4-x^2-42=0 <br>need to solve equation and find solution set
Ipatiy [6.2K]
That's a quadratic equation in x^2, which means we get an extra square root and \pm at the end.

x^4 - x^2 - 42 = 0

We factor,

(x^2 - 7)(x^2+6) = 0

x^2 = 7 \quad \textrm{or} \quad x^2 = -6

x = \pm \sqrt{7} \quad \textrm{or} \quad x = \pm i \sqrt{6}

Georgia [21]

Answer:

The total number of pages in all the newspaper is 390,625 pages

Step-by-step explanation:

The number of pages in the newspaper = 25 pages

The number of schools ordering the newspaper = 25 schools

The number of class rooms in each school = 25 classrooms

The number of students in each classroom = 25 students

Therefore;

The total number of pages in all the newspaper = 25 pages per paper × 25 schools × 25 classroom per school × 25 students per classroom

The total number of pages in all the newspaper = 25 × 25 × 25 × 25 = 25⁴

The total number of pages in all the newspaper = 25⁴ = 390,625 pages

<h2>Hey there </h2>

<h2>Answer:</h2>

<h3>- 1976</h3>

<h2>Step-by-step explanation:</h2>

{5x}^{2}  - 5x - 169 =  {2x}^{2}  + x + 5 \\  \\  {5x}^{2}  - 5x - 169 -  {2x}^{2}  - x + 5 = 0 \\  \\  {3x}^{2}  - 4x - 164 = 0

<h2>Therefore, finding the discriminant:</h2>

<h3>a = 3 b = -4 c = 164</h3>

<h3>We, know that to find discriminant. </h3>

<h3>b^2 - 4.a.c</h3>

<h3>(-4)^2-4.3.164</h3>

<h3>-8 - 1968</h3>

<h3>- 1976</h3>

<h2>Hope it help you</h2>
