Question

The solution of the quadratic equation 3x^2=4x is written by a student as the following: According to you, is this students solution correct or not? Explain your answer with reasons?

Solution:
Step 1:3x2 = 4x
Step 2: 3xx = 4x
Step 3:3x = 4
Step 4: x = 4/3​

Answer 1

Well the answer is correct but the working out is wrong because you are supposed to subtracts 4x by both sides first then factor out x thirdly find the equation solutions and then solve



Step 1) 3x^2 - 4x = 0
Step 2) x(3x - 4) = 0
Step 3) x = 0
Step 4) 3x - 4 = 0 + 4 hereby leaves 3x = 4
Step 5) x = 0 and x = 4/3
