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

Answer: What is the question
Step-by-step explanation:
Answer:
2.5
Step-by-step explanation:\
