Answer 1

Respuesta:

a. (x+6)(x+10) =  $x*x+x*10+6*x+6*10=x^{2} +16x+60$

b. (x-2)(x-3) = $x*x-3*x-2*x-2*(-3) = x^{2} -5x+6$

c. (2x+5)(x+4) = $2x*x+2x*4+5*x+5*4= 2x^{2} +8x+5x+20 = 2x^{2} +13x+20$

d. (5x+9)(x-1) =$5x*x+5x*(-1)+9*x+9*(-1) = 5x^{2} -5x+9x-9 = 5x^{2} +4x-9$

e. (4x+3)(x+2) = $4x*x+4x*2+3*x+3*2 = 4x^{2} +6x+3x+6 = 4x^{2} +9x+6$
