Answer:

x =2 or x=7

Step-by-step explanation:

x^2-9x+14= 0

Now splitting the middle term we get,

x^2-7x -2x +14 =0

x(x-7) - 2(x-7) =0

(x-2) (x-7) =0

x-2=0 or x-7 =0

x =2 or x=7

Answer:

Step-by-step explanation: 1. What are the factors of the last term, 14. are 2, 2. The factors of 14 are 1, 2, 7, 14.

3. What two factors of 14 can I add to get the middle term of 9?

4. The answer is: 2 and 7

5 So the factored answer is (x+2)(x=7)

Vertex is at $\left(-3,-6\right)$

y-intercept is 3.

The parabola opens up.

Step-by-step explanation:

The graph of the equation is hereby attached in the answer area.

Vertex is the point on the parabola where the graph crosses its axis of symmetry. The axis of symmetry here( $x =-3$ ), is shown with the dotted line in the graph attached.

y-intercept is defined as the value of y where the graph crosses the y-axis. In other words, when $x=0$ . Putting

And, the graph opens up as shown the graph figure as well. It is also evident from the co-efficient of $x$ in the given equation $y =x^{2} + 6x + 3$ . Here, co-efficient of
