Which expression represents a quadratic expression in complete factored form? +4)(x-3) -1)(3x-9) +4)(x-3) -2)+(x+3)

Thus, (x - 2) + (x + 3) is not a quadratic equation. Then A, B, and C are the quadratic equation.

It is a polynomial of maximum power 2. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.

A.  (2x + 4)(x - 3)

On multiplying

2x² - 2x -12

B.  (x - 1)(3x - 9)

On multiplying

3x² -12x + 9

C.  (x + 4)(x - 3)

On multiplying

x² + x - 12

D.  (x - 2) + (x + 3)

On multiplying

2x + 1

Thus, (x - 2) + (x + 3) is not a quadratic equation. Then A, B, and C are the quadratic equation.

C

Step-by-step explanation:

A) not completely factored because 2 can be factored out of 2x + 4

B)  not completely factored because 3 can be factored out of 3x - 9

C) CORRECT

D) not factors because the terms are added instead of multiplied

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

the anwser is d) 75°
