Answer:

B

Step-by-step explanation:

The steps to bring equation to standard form is Distribute the 3x and then subtract 9 from both sides of the equation

What is standard form of equation?

The standard form for linear equations in two variables is Ax+By=C.

For example, 2x+3y=5 is a linear equation in standard form.

According to the question

3x (2x - 7) = 9

Now,

Step1: Multiply 3x to the braces part

6[tex]x^{2}[/tex] - 21 = 9

Step 2 : Subtract 9 both side

6[tex]x^{2}[/tex] - 30 = 0

Its standard form

Hence, The steps to bring equation to standard form is Distribute the 3x and then subtract 9 from both sides of the equation
