Find the solutions to 6x^2- 54x = 0
Nina [5.8K]

Answer:      

A. x = 9

D. x = 0

Step-by-step explanation:

The formula to solve a quadratic equation of the form

ax^{2} +bx+c=0

is equal to

x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}

in this problem we have            

6x^{2} -54x=0              

so

a=6\\b=-54\\c=0

substitute in the formula

x=\frac{-(-54)(+/-)\sqrt{-54^{2}-4(6)(0)}} {2(6)}

x=\frac{54(+/-)54} {12}

x=\frac{54(+)54} {12}=9              

x=\frac{54(-)54} {12}=0          

therefore

The solutions are x=0 and x=9
