Which two values of x are roots of the polynomial below?

Julli [10]

Answer:

B. and C.

Step-by-step explanation:

1. Set the polynomial equal to zero:

x² + 5x + 7 = 0

2. Plug the given values of a, b, and c into the quadratic formula:

$x=\frac{-5+-\sqrt{5^{2}-4(1)(7) } }{2(1)}$

3. Solve the square root:

$x=\frac{-5+-\sqrt{25-4(1)(7)} }{2(1)}$

$x=\frac{-5+-\sqrt{25-28} }{2(1)}$

$x=\frac{-5+-\sqrt{-3} }{2(1)}$

4. Simplify the rest:

$x=\frac{-5+-\sqrt{-3} }{2}$

5. Separate the solutions:

$x=\frac{-5+\sqrt{-3} }{2} , x=\frac{-5-\sqrt{-3} }{2}$

Thus, options B and C are the answers.

hope this helps!

What are the x-intercepts of y=x^2+2x-15

Sedbober [7]

Answer:

$(-5,0)$ and $(3,0)$

Step-by-step explanation:

Think about it.

What two numbers multiply to -15 and add up to 2?

The answers are 5 and -3.

So plug that into the factored form of a parabola.

$y=(x+5)(x-3)$

To find the x-intercepts, plug in 0 for $y$ .

$(x+5)(x-3)=0$

Since we are multiplying, at least one of the terms has to equal 0.

$x+5=0 \\ x-3=0 \\ \\ x=-5,3$

So the x-intercepts are $(-5,0)$ and $(3,0)$ .
