Find a polynomial P(x) with the zeros x=2, −(2), √3, −√3

Mathematics
1 answer:
Zigmanuir [339]3 years ago
6 0

Answer:

P(x) = x^{4} - 7x² + 12

Step-by-step explanation:

Given zeros x = 2, x = - 2, x = \sqrt{3}, x = - \sqrt{3}

Then the factors are (x - 2), (x + 2), (x - \sqrt{3} ), (x + \sqrt{3} )

and the polynomial is the product of the factors, that is

P(x) = (x - 2)(x + 2)(x - \sqrt{3} )(x + \sqrt{3} ) ← expand in pairs using FOIL

      = (x² - 4)(x² - 3) ← distribute

     = x^{4} - 3x² - 4x² + 12 ← collect like terms

    = x^{4} - 7x² + 12

Solve the Equations
Vikentia [17]

Answer:

1) -2.13

2) 2.57

3) 33

Step-by-step explanation:

1)

3(8 + 5h) = -28  Distribute the 3

24 + 15h = -28  Subtract 24 from both sides of the equation

15h = -32  Divide both sides by 15 and round

h = - 2.13

2)

19 = 7(3n - 5)  Distribute the 7

19 = 21n - 35  Add 35 to both sides of the equation

54 = 21n  Divide both sides of the equation by 21

2.57 = n

3)

6s - 7s = -33  Combine the s's

-s = -33  Multiply both sides by -1

s = 33

What is the solution for −40 = 10c? <br> A. c = 1 <br> B. C = -1 <br> C. c = -4 <br> D. c = 4
Aleks [24]

Answer:

C. c = -4

Step-by-step explanation:

you must get c by itself. you have to divide both sides by 10. this gets rid of the 10c and keeps both sides equal

-40/10 = c

c = -4
