Answer:
The linear term is -5x
Step-by-step explanation:
The linear term is the term that has the degree equal to 1.
The given function is
y = 2x^2 − 5x − 12
here 2x^2 = quadratic term i.e having degree 2
-5x = linear term i.e having degree 1
-12 = constant
so, The linear term is -5x
The entry in row 1, column 1 of
is

(i.e. the dot product of row 1 of
and column 1 of
)
The entry in row 1, column 2 of
is

The second option is the correct answer.
Using the information from the question, one can construct two equations:

... (1)

... (2)
by substituting (1) into (2) to find x


\frac{5}{4z} = \frac{1}{4}



⇒ z = 5
By substituting value of z into (1)
⇒ 4 (5) = x
⇒ x = 20
Thus the two numbers are 5 & 20
