Answer:

Step-by-step explanation:
x² - 3 = 2x ( subtract 2x from both sides )
x² - 2x - 3 = 0 ← in standard form
consider the factors of the constant term (- 3) which sum to give the coefficient of the x- term (- 2)
the factors are - 3 and + 1 , since
- 3 × + 1 = - 3 and - 3 + 1 = - 2 , then
x² - 2x - 3 = (x - 3)(x + 1) = 0 ← in factored form
equate each factor to zero and solve for x
x + 1 = 0 ⇒ x = - 1
x - 3 = 0 ⇒ x = 3
