Question

Which of the following is the equation for x: ax^2 = bx? select all that apply.

Answer 1

Answer:

• x = 0

• x = b/a

Step-by-step explanation:

Subtract the term on the right and factor:

ax^2 -bx = 0

x(ax -b) = 0

The zero product rule lets you write this as two equations:

x = 0

ax -b = 0

The latter can be rearranged to ...

ax = b

x = b/a

Of the choices shown, the equations for x are ...

x = 0

x = b/a
