Write the quadratic equation in general quadratic form below.<br> 17x² = 12x
marusya05 [52]

Answer:

17x² - 12x + 0 = 0

Step-by-step explanation:

We can move all the terms to the same side of the equation first:

17x²=12x

17x² - 12x = 0

We know that a standard quadratic equation is in the form ax² + bx + c = 0, so we can substitute our values into this equation to match its form.

a=17

b=12

c=0

17x² - 12x + 0 = 0
