(i) \((4n)^2 - 2n + 3 = 4n^2 - 2n + 3\)

Correct answer: \((4n)^2 - 2n + 3 =\)

i i^{i} - i i + i

(ii) \((x - 2)(x + 3) = x^2 - 6\)

Correct answer: \((x - 2)(x + 3) =\)

i^{i} + i - i

(iii) \(-3p^2 + 4p - 7 = -(3p^2 + 4p - 7)\)

Correct answer: \(-3p^2 + 4p - 7 =\)

- (i i^{i} - i i + i)

(Note: Enter the number followed by the variable and then its exponents.)
