Roots: - √5 , √5, and - 3

=> these are factors of the polynomial: (x + √5), (x - √5), and (x + 3).

Multiply those three factors:

(x + √5) (x - √5) ( x + 3) = [x^2 - 5] ( x + 3 ) = x^2 + 3x^2 - 5x - 15

Therefore the polynomial x^2 + 3x^2 - 5x - 15 is a polynomial with the given roots.

Answer: option B. x^3 + 3x^2 - 5x - 15

Answer:

$m = \frac{-y+x}{2}$

Step-by-step explanation:

$2m - x + 3y = 2y$

Take $-x$ and $+3y$ on the other side of the equal to sign:

$2m = 2y +x-3y$

Now solve for y:

$2m = -y +x$

Take 2 one the other side of the equation:

$m = \frac{-y +x}{2}$

Hope this helps :)

Answer:

x = $\sqrt{1}$

Step-by-step explanation:

(x + 6 )^2 = 49

get rid of the square , by square rooting the 49

x + 6 = $\sqrt{49}$

x = $\sqrt{49}$ -6

x = $\sqrt{1}$

$\sqrt{49}$ means + or - hence it could be -7 -6 = -1 ... or 7-6 = 1

therefore the answer is = or - 1

hence in terms of roots .. answer is :

$\sqrt{1}$
