(a) : (a+1)(a+2)
(b) :(r+5)(r-3)
(c) :(x+3)(x+4)
(d) :(3m-5)(2m-1)
(e) :(y+2)²
(f) :(x+6)(x-6)

Answer 1

Boa Noite Jennyffer!!!

(a) : (a+1)(a+2) = a² + 3a + 2

(b) :(r+5)(r-3) = r² +2r -15

(c) :(x+3)(x+4) = x² + 7x + 12

(d) :(3m-5)(2m-1) = 6m² -13m + 5

(e) :(y+2)²=y² + 4y + 4

(f) :(x+6)(x-6) = x² + 12x + 36
