3x(x-2) = 0<br> in standard form and its roots

slava [35]

Answer:

Step-by-step explanation:

Let's solve your equation step-by-step.

3x(x−2)=0

Step 1: Simplify both sides of the equation.

3×2−6x=0

For this equation: a=3, b=-6, c=0

3×2+(−6x)+0=0

Step 2: Use quadratic formula with a=3, b=-6, c=0.

$x=\frac{-b ±\sqrt{b^2-4ac} }{2a}$

x=2 or x=0

hope it helps other wise I am sorry
