Answer: k = {8, -8}
<u>Step-by-step explanation:</u>
In order for a quadratic equation to have exactly one solution, the discriminant must equal zero. → b² - 4ac = 0
4x² + kx + 4 = 0
↓ ↓ ↓
a=4 b=k c=4
b² - 4ac = 0
k² - 4(4)(4) = 0
k² = 64
k = √64
k = ± 8
He didn’t multiply the equation by 1/2 in the second part so it threw his whole answer off. Hope this helps
Step-by-step explanation:

The quotient of
divided by
is (x-2_.
Given the polynomial
and
and the first expression or polynomial is divided by second.
Quotient is a number that is obtained by dividing two numbers. It can be of two numbers or two expressions. Remainder is a number or an expression left after division of two numbers.
To find the quotient of
divided by , we have to divide the expression first.
We know that ,
Divident=Divisor*Quotient+remainder
=
*(x-2)-12
If we carefully watch the above equation and compares with the above formula then we can easily find that the value of quotient is (x-2).
Hence the quotient of
divided by
is (x-2).
