Answer:

1. QE

Explanation:

We need to convert the equation into its standard form.

6=7x \ (4x)6=7x (4x)

6=28x^{2}6=28x

2

\begin{gathered}28x^{2}=6\\\end{gathered}

28x

2

=6

28x^{2}-6=028x

2

−6=0

2. QE

Explanation:

It is already on its standard form and it is equated to 0.

3. QE

Explanation:

Using the FOIL Method, convert the factored form into standard form.

\begin{gathered}(a-8)(a+5)=14\\a^{2} +5a-8a-40=14\\a^{2} -3a-40-14=0\\a^{2} -3a-54=0\end{gathered}

(a−8)(a+5)=14

a

2

+5a−8a−40=14

a

2

−3a−40−14=0

a

2

−3a−54=0

4. NQE

Explanation:

Transpose 10 to the other side.

\begin{gathered}5x+5y=10\\5x+5y-10=0\end{gathered}

5x+5y=10

5x+5y−10=0

5. QE

Explanation:

\begin{gathered}7=8m^{2} -2m\\8m^{2} -2m-7=0\end{gathered}

7=8m

2

−2m

8m

2

−2m−7=0
