Resolver FACTORIZACIÓN DE TRINOMIOS CUADRADOS PERFECTOS.

1. x²-10x+25=

2. 4x² + 12xy + y²=

3. 16x² + 8xy + y²=

Answer 1

Respuesta:

${x}^{2} - 10x + 25 = {x}^{2} - 2(x)(5) + {5}^{2} = {(x - 5)}^{2}$

$4 {x}^{2} + 12xy + 9 {y}^{2} = {(2x)}^{2} + 2(2x)(3y) + {(3y)}^{2} = {(2x + 3y)}^{2}$

${16x}^{2} + 8xy + {y}^{2} = {(4x)}^{2} + 2(4x)(y) + {y}^{2} = {(4x + y)}^{2}$
