Which is the completely factored form of 4x2 + 28x + 49? (x + 7)(4x + 7) 4(x + 7)(x + 7) (2x + 7)(2x + 7) 2(x + 7)(x + 7)

Option C- Factored form of

Step-by-step explanation:

Given : Quadratic equation

To find : The complete factor of the given quadratic equation

Solution :

We have to find the roots of the quadratic equation using discriminant method.

General form -

Solution is

Comparing with equation is

where a=4 , b=28, c=49

Solution is

The roots are

or we can write as

Therefore, Option C is correct.

Factored form of

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
