Answer:
m=12
Explanation:
Given any quadratic function, y=ax²+bx+c.
We can determine the nature of the roots of such quadratic function by examining the discriminant, D where:

• If D>0, the roots are real and unequal.
,
• If D=0, the roots are real and equal.
,
• If D<0, the roots are complex.
In our given equation:

For the function to have exactly one zero, the value of D=0.

The value of m for which the function will have one zero is 12.

Answer:
Option a) is correct that is -49.
Step-by-step explanation:
We have been given the two functions in which one of them is dividend and the other one is divisor
when divided by x+2
You can see the long division to find the remainder in the attachment.
First step we do is to choose the quotient so as to cancel the first term
And proceed till you get the degree of divisor less than dividend.
Hence, the remainder we will get is -49
Therefore, option a) is correct.
