rozłóż na czynniki metodą skróconego mnozenia w(x)=-25x^2-20x-4 w(x)=x^3-3x^2+3x-1 w(x)=1+6x+12x^2+8x^3 w(x)=(9x^2-6x+1)-(4x^2+20x+25)

w(x)=-25x^2-20x-4 = -(5x + 2)² w(x)=x^3-3x^2+3x-1 = (x - 1)³ w(x)=1+6x+12x^2+8x^3 = (2x + 1)³ w(x)=(9x^2-6x+1)-(4x^2+20x+25) = (3x-1)²-(2x+5)²

w(x)=-25x^2-20x-4 w(x)=-(25x^2 +20x + 4) w(x)=-[(5x)^2 + 2*5x*2 + 2^2] w(x) = -(5x+2)^2 ___________________________ w(x)=x^3-3x^2+3x-1 w(x)= x^3 - 3 * x^2 * 1 + 3 * x * 1^2 - 1^3 w(x) = (x-1)^3 _____________________________________ w(x)=1+6x+12x^2+8x^3 w(x)=1^3 + 3*1^2 *2x+3*1*(2x)^2+(2x)^3 w(x)=(1+2x)^3 _____________________________________ w(x)=(9x^2-6x+1)-(4x^2+20x+25) w(x)=(3x-1)^2 - (2x+5)^2
