Answer:

smaller r = -10

larger r = 6

The ordered pair for the vertex of the parabola is (-2,-64)

Step-by-step explanation:

We have the function f(r)=r^2+4x-60

In order to factor this quadratic equation, we need to look for two numbers that will

Add together to get 4

Multiply together to get -60

Lets look for the numbers that multiply to give us -60.

-1 and 60

1 and -60

2 and -30

-2 and 30

3 and -20

-3 and 20

4 and -15

-4 and 15

5 and -12

-5 and 12

6 and -10

-6 and 10

Now, we just need to determine which of these numbers will add together to get us 4.

Those two numbers would be -6 and 10.

This means that our factored form of this equation will be

f(r)=(r-6)(r+10)

From this, we can find our roots, which are the solutions to the equation when it is equal to 0.

(r-6)(r+10)=0\\\\r=-10, r=6

These are our r values.

The vertex of a parabola will always be directly between the two roots.

The number that is between -10 and 6 is r=-2

To find the y-value of the coordinate pair, we just need to plug -2 into our function.

f(-2)=(-2)^2+4(-2)-60\\\\f(-2)=4-8-60\\\\f(-2)=-64

This means that the ordered pair for the vertex of the parabola is (-2,-64)

Naddika [18.5K]

Step-by-step explanation:

7x+10 - (x+2)^2

7x+10 - (x^2 + 2x + 4)

7x+ 10 - x^2 - 2x - 4

5x + 6 - x^2

then if u have to find the value of x then put the value of a = 1,b = 5,c = 6 in quadratic formula (-b + under root b^2 - 4ac / 2a) or (- b - under root b^2 - 4ac / 2a) it will gives the value of x...

HOPE it u..!!

edit - do let me knw that it's right or not..!!
