Answer:
plz mark as brain list
Step-by-step explanation:
⟹ 2x 2 – 5x + 2 = 0
⟹ 2x 2 – 4x – x + 2 = 0
⟹ 2x (x – 2) – 1(x – 2) = 0
⟹ (x – 2) (2x – 1) = 0
Equate each factor equal to zero and solve
⟹ x – 2 = 0 or 2x – 1 = 0
⟹ x = 2 or x = 1212
Therefore, the solutions are x = 2, 1/2.
Example 2
Solve 3x 2 – 8x – 3 = 0
