AYUDAAAAAAA PORFAVOR ES PARA Hoy!!! bueno gracias :"b​

Answer 1

Respuesta:

E = (x+3)(x+5)+(x-2)(x-4)-2x(x+1)-18

E = ((x+3)(x+5))-((x-2)(x-4))-2x(x+1)-18

E = ((x)²+(3+5)x+(3×5))-((x)²+(-2-4)x+(-2(-4))-2x(x+1)-18

E = (x²+8x+15)-(x²+(-6x)-(-8))-2x(x+1)-18

E = x²+8x+15-(x²-6x-(-8))-2(x(x+1))-18

E = x²+8x+155-(x²-6x+8)-2(x²+x)-18

E = x²+8x+15-x²+6x-8-2x²-2x-18.

E = (1-1-2)x²+(8+6-2)x+(15-8-18)

E = (0-2)x²+(14-2)x+(7-18)

E = -2x²+12(x)+(-11)

E = -2x²+12x-11

R// El valor de calcular " E = (x+3)(x+5)+(x-2)(x-4)-2x(x+1)-18 " es " E = -2x²+12x-11 " .
