[tex]\huge\text{Hey there!}[/tex]
[tex]\huge\textbf{Equation:}[/tex]
[tex]\mathbf{x^2 + 7x = 30}[/tex]
[tex]\huge\textbf{Solving for the equation: }[/tex]
[tex]\mathbf{x^2 + 7x = 30}[/tex]
[tex]\huge\textbf{Subtract \boxed{\bf 30} to both sides:}[/tex]
[tex]\mathbf{x^2 + 7x - 30 = 30 - 30}[/tex]
[tex]\mathbf{x^2 + 7x = 30 - 30}[/tex]
[tex]\mathbf{x^2 + 7x = 0}[/tex]
[tex]\huge\textbf{Factor the left side of the equation:}[/tex]
[tex]\mathbf{(x - 3)(x + 10) = 0}[/tex]
[tex]\huge\textbf{Set the factors to equal to 0:}[/tex]
[tex]\mathbf{x - 3 = 0\ or\ you\ can\ say\ x + 10 = 0}[/tex]
[tex]\huge\textbf{Simplify it:}[/tex]
[tex]\mathbf{x = 3\ or\ x = -10}[/tex]
[tex]\huge\textbf{Therefore, your answer should be:}[/tex]
[tex]\huge\boxed{\mathsf{\boxed{\frak{Option \ C.}} x = -10\ or \ x = 3}}\huge\checkmark[/tex]
[tex]\huge\text{Good luck on your assignment \& enjoy your day!}[/tex]
