4. An interesting thing happens when you multiply two conjugate binomials. Conjugates have the property of having the same terms but differ by the operation between the two terms (in one case addition and in one case subtraction). Multiply each of the following conjugate pairs and state your answers in standard form. The first is done as an example (a) (x+3)(x-3) = x(x-3)+3(x-3). = x-3x+3x-9 = x-9 (b) (x-5)(x+5) (c) (10+x)(10-x) (d) (2t+3)(2t-3) (e) (5t+1)(St-1) (f) (8-3t) (8+3t) 1
