Answer:

All real numbers are solutions.

Step-by-step explanation:

Let's solve your equation step-by-step.

−28+4x=4(x−7)

Step 1: Simplify both sides of the equation.

−28+4x=4(x−7)

−28+4x=(4)(x)+(4)(−7)(Distribute)

−28+4x=4x+−28

4x−28=4x−28

Step 2: Subtract 4x from both sides.

4x−28−4x=4x−28−4x

−28=−28

Step 3: Add 28 to both sides.

−28+28=−28+28

0=0

Answer:

x^2 + 5 x + =0

Step-by-step explanation:

We need to factor this trinomial by grouping.

The first step in this process consists of splitting the middle term into two terms.

In our example, 5x  has been split into 2x and .

Notice that one common factor can be factored from the first 2 terms, and another from the second 2 terms
