Question

(5x + 10 )2 (r- 3s)2 (5 + 1/2x)2 son binomios cuadrados

(a + 9) (a-6) (a - 3)3 (2/3x + 9y)2 de productos notables

Answer 1

(5X+10)² = 25X²+100X+100
(R-3S)²=R²-6RS+9S²
$( \frac{5} +{1/2X} ) ^{2}$ =25+5X+$\frac{ x^{2} }{4}$
(A+9)(A-6)=A²+3A-54
(A-3)³=A³+9A²-54
$(\frac{2}{3}X+9Y) ^{2}$=$\frac{4 x^{2} }{9} + \frac{36XY}{3} +81 Y^{2}$
