Question

Алгебра 8клас, срочно​

Answer 1

$2x^2+16x+25=2(x^2+8x+\frac{25}{2})=2(x^2+8x+16-16+12,5)=2((x+4)^2-3,5)=2(x+4)^2-7\\\frac{2x^2+4x+2}{3x^2+6x-9}=\frac{2(x^2+2x+1)}{3(x^2+2x-3)} =\frac{2(x+1)^2}{3(x^2+2x+1-4)}=\frac{2(x+1)^2}{3((x+1)^2-4)}=\frac{2(x+1)^2}{3(x+1-2)(x+1+2)}=\frac{2(x+1)^2}{3(x-1)(x+3)}$
