Answer:
true/ true/ false/ true
Step-by-step explanation:
4x² is a term in both the numerator and denominator → Correct
factorise numerator and denominator
4x² - 4 = 4(x² - 1) ← common factor of 4
x² - 1 ← is a difference of squares and factors as
(x - 1)(x + 1)
4x² - 3x - 1 = (4x + 1)(x - 1) ← in factored form
Hence (x - 1) is a common factor in the numerator and denominator → Correct
4 is only a common factor in the numerator not the denominator
the denominator has three terms → Correct
being 4x² , - 3x and - 1
