Which two values of x are roots of the polynomial below? x^2-3x+5

Gemiola [76]

Given:

Polynomial $x^2-3x+5$

To find:

The values of x.

Solution:

$x^2-3x+5=0$

Quadratic equation formula:

$$x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}$

Here $a=1, b=-3, c=5$ .

Substitute the values in the formula, we get

$$x=\frac{-(-3) \pm \sqrt{(-3)^{2}-4 \cdot 1 \cdot 5}}{2 \cdot 1}$

$$x=\frac{3 \pm \sqrt{9-20}}{2}$

$$x=\frac{3 \pm \sqrt{-11}}{2}$

$$x=\frac{3 - \sqrt{-11}}{2} \ \text{and} \ x=\frac{3 + \sqrt{-11}}{2}$

Option E and option F are the roots of the polynomial.

The values of x are $x=\frac{3 - \sqrt{-11}}{2} \ \text{and} \ x=\frac{3 + \sqrt{-11}}{2}$ .

Which equation is the result of adding these two equations -2x+4y=17

Katyanochek1 [597]

The right answer is Option C.

Step-by-step explanation:

Given equations are;

-2x+4y=17 Eqn 1

3x-10y= -3 Eqn 2

Adding Eqn 1 and Eqn 2;

$(-2x+4y)+(3x-10y)=17+(-3)\\-2x+4y+3x-10y=17-3\\3x-2x-10y+4y=14\\x-6y=14$

The right answer is Option C.
