We know for our problem that the zeroes of our quadratic equation are

and

, which means that the solutions for our equation are

and

. We are going to use those solutions to express our quadratic equation in the form

; to do that we will use the <span>zero factor property in reverse:
</span>



<span>
</span>



<span>
Now, we can multiply the left sides of our equations:
</span>

<span>= </span>

=

=

Now that we have our quadratic in the form

, we can infer that

and

; therefore, we can conclude that

.

option D
Step-by-step explanation:
Answer:
The temperature rose by 5 degrees celcius between 11 am and 4 pm
Step-by-step explanation:
Here in this question, we want to find the integer which represents the temperature change from 11 am to 4 pm.
Initially, in the morning, the temperature was -2 . By 11, it had decreased by 3 degrees. What this means is that the temperature went down further by 3 degrees.
Mathematically, the temperature at 11 will be -2-3 = -5 degrees celcius
Now at 4 pm, the temperature went from -5 to 0 degrees.
The temperature change between 11 am and 4 pm will be; 0-(-5) = 0 + 5 = 5 degrees celcius
This means that the temperature rose by 5 degrees celcius between 11 am and 4 pm
