esos cuadraditos de lps ejercicios 3 al 6 que son mas(+) o menos (-) o son para completar
1) [5g-2h^(2)]^2
7²x^(8)+14x⁴y+8²y⁴= (7x⁴)²+14x⁴y+(8y²)²=
(7x⁴)²+14x⁴y+(8y²)²+ 2*(7x⁴)*(8y²)- 2*(7x⁴)*(8y²)= (7x⁴)²+14x⁴y+(8y²)²+112x⁴y²- 112x⁴y²=(7x⁴+8y²)²-112x⁴y² +14x⁴y => (7x⁴+8y²)²=112x⁴y² =14x⁴y
(7x⁴)²+14x⁴y+(8y²)²+ 2*(7x⁴)*(8y²)- 2*(7x⁴)*(8y²)= (7x⁴)²+14x⁴y+(8y²)²+112x⁴y²- 112x⁴y²=(7x⁴+8y²)²-112x⁴y² +14x⁴y => (7x⁴+8y²)²=112x⁴y² =14x⁴y
3 ) 9m^(6)+45n²+64y⁴= (3m³)²+45n²+(8y²)²= (3m³)²+45n²+(8y²)²-2*3*8m³y²+ 2*3*8m³y²= (3m³)²+45n²+(8y²)²+48m³y- 48m³y= (3m³+8y²)²-48m³y +45n² => (3m³+8y²)²=48m³y² -45n
4) (b+d)²
