Find all roots x^3 + 7x^2 + 12x = 0

babunello [35]

Answer:

Therefore the THREE roots are

$x=0\ or\ x=-3\ or x=-4$

Step-by-step explanation:

Given:

$x^{3}+7x^{2} +12x= 0$

To Find:

All the Roots = ?

Solution:

As the degree of the polynomial is THREE then the number of root are also THREE.

$x^{3}+7x^{2} +12x= 0\\\\x(x^{2}+7x +12)= 0\\\\x=0\\or\\x^{2}+7x +12= 0\\$

Now one root is Zero For other we need to Factorize

So by Splitting the middle term

i.e Factor of 12 such that sum should be 7

i.e 3 × 4 = 12 and 3 + 4 = 7

∴ $x^{2}+7x +12= 0\\x^{2}+3x+4x +12= 0\\x(x+3)+4(x+3)=0\\(x+3)(x+4)=0\\\\x+3=0\ or\ x+4 = 0\\\\\therefore x=-3\ or x=-4\ \textrm{Which are the roots}$

Therefore the THREE roots are

$x=0\ or\ x=-3\ or x=-4$

PLEASE HELP ASAP! and thank you if you do

Answer: 600, 648, kite

Step-by-step explanation:

area of trapezoid

use formula h(b1+b2)/2

h = 12

b1 = 44

b2 = 56

plug in numbers to get

12(44+56)/2

= 600

area of kite

use formula pq/2

p = height = 12 + 12 = 24

q = length = 44 + 10 = 54

plug in numbers to get

24*54/2

= 648

larger area

since 600 < 648, max will choose the kite
