Answer 1

Let's analyze the information provided and correct the steps to factor out the Greatest Common Factor (GCF) and solve the quadratic equation $722=56x$.

1. Put the quadratic in standard form: The original equation is $722=56x$. Rearranging this to standard form (0 on one side) gives: $$56x-722=0$$ To put it in standard quadratic form $7x^2+56x=0$, we must first clarify the equation. It seems you intended to write $7x^2+56x=0$ with a GCF of 7 factored out from a related equation. We have: $$7x^2+56x=0$$

2. Factor out the GCF: The GCF of $7x^2$ and $56x$ is $7x$: $$7x(x+8)=0$$

3. Set each factor equal to zero: From the factored form $7x(x+8)=0$, set each factor equal to zero: $$7x=0\text{and}x+8=0$$

4. Solve for $x$:

   • From $7x=0$: $$x=0$$
   • From $x+8=0$: $$x=-8$$

Final Solutions: The solutions are $x=0$ and $x=-8$.

Correct Steps:

1. Put the quadratic in standard form: $7x^2+56x=0$
2. Factor out the GCF: $7x(x+8)=0$
3. Set each factor equal to zero: $7x=0$ and $x+8=0$
4. Solutions are $x=0$ and $x=-8$.
