--First we have to simplfy
--Cancel common factors
--Here remember never cancel factors in a subtraction or addition problem
--Now Multiply each side until both denominators are equal to each other
--Simplify
--Now that the denominators are the same: subtract!
--And LAST STEP! ......Simplify More.... To get your answer
The quadratic function are:
option: A A) y(y + 4) - y = 6
Option: C C.) 4b(b) = 0
<h2>Step-by-step explanation:</h2>We know that the general equation of a quadratic equation in terms of a variable x is given by:
A)
y(y + 4) - y = 6
On simplifying the terms we have:
Hence, option: A is correct.
B)
(3x + 2) + (6x - 1) = 0
Hence, it is a linear equation.
Hence, option: B is incorrect.
C)
4b(b) = 0
it could also be written as:
Hence, it is a quadratic equation.
Hence, option: C is correct.
D)
3a - 7 = 2(7a - 3)
which is again a linear equation.
Hence, option: D is incorrect.
