X^3 + 2x - 3

Just divide x^5-3x^3-3x^2-10x+15 by the quotient and you get the polynomial searched.

Answer:

x^3+2x-3    

Step-by-step explanation:

the quotient of (x^5 - 3x^3 - 3x^2 - 10x+15)and a polynomial is (x^2 -5)

\frac{x^5 - 3x^3 - 3x^2 - 10x+15}{x^2-5}

WE use long division

                                                  x^3+2x-3                    

                                      -------------------------------------------------

(x^2-5)           x^5 - 0x^4-3x^3 - 3x^2 - 10x+15

                                   x^5 +0x^4 -5x^3    

                                  --------------------------------------------------(subtract)

                                                    2x^3 - 3x^2-10x

                                                    2x^3 + 0x^2 -10x

                              ------------------------------------------------------(subtract)

                                                             -3x^2+0x+15

                                                             -3x^2+ 0x +15

                              -----------------------------------------------------(subtract)

                                                                    0

What's the solution to x^2-11x+19=-5<br> (this is a Quadratic Equation)
Maru [420]

Answer:

8 and 3

Step-by-step explanation:

We first want to add 5 to both sides, making the equation x^2 -11x +24=0, now, we want to use the quadratic formula, which is( -b <u>+</u> sqrt(b^2 -4ac)) /2a  

for equations of the form ax^2 + bx +c, so in our case, a =1, b=  -11, and c=24,

when you plug in the variables, you will get the answers!   :)
