 $\bold{Hello!}\\\bold{Your~Answer~Is~Below!}$

______________________________

 $\bold{Solution~Steps:}$

1.) Input $a=4$, $b=3$, and $c=9$ into the equation.

• $\frac{4^2-2*3*9}{7}$

2.) Calculate 4 to the power of 2.

• $4^2=16$

• Equation at the end of this step: $\frac{16-2*3*9}{7}$

3.) Multiply 2 and 3.

• $2$ × $3=6$

• Equation at the end of this step: $\frac{16-6*9}{7}$

4.) Multiply 6 and 9.

• $6$ × $9=54$

• Equation at the end of this step: $\frac{16-54}{7}$

5.) Subtract 54 from 16.

• $16-54=-38$

• Equation at the end of this step: $\frac{-38}{7}$

6.) Fraction $\frac{-38}{7}$ can be rewritten as a decimal by dividing:

• $-38$ ÷ $7=-5.42857143$
