Which expression is equivalent to 2x² + 7x + 4?

A.
(2x − 1)(x + 4)

B.
(2x + 1)(x − 4)

C.
(2x + 1)(x + 4)

D.
None of these

none of these

Step-by-step explanation:

2x² + 7x + 4

Factor

We cannot factor this since 2*4 +1 = 9 and we want 7

and 2*2 +2 = 6 and we want 7

and 2*1 +4 = 6 and we want 7

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.
