Answer»

(1) (-13/5 + 12/7) ÷ (-13/7 * - 1/2)= (-13*7 + 12*5)/35 ÷ 13/14= (-91 + 60)/35 * 14/13= - 31/35 * 14/13= - 31*2/5*13= - 62/65

(2) x^2 + 5x + 6= x^2 + 3x + 2x + 6= x(x + 3) + 2(x + 3)= (x + 2)(x + 3)

On division by (x + 2), we get(x + 3)

x²+5x+6=x²+2x+3x+6=x(x+2)+3(x+2)=(x+3)(x+2)(x+3)(x+2)/(x+2)=(x+3)
