Question

Factorar o descomponer en dos factores 1. X^2+7x+10= 2.X^2-5x+6= 3.X^2+x-2= 4.X^2-3x= 5.N^2-6n-40= 6.X^2+10x+21= Por favor lo mas rápido posible

Answer 1

Explicación paso a paso:

1) X^2+7x+10=

${x}^{2} + 7x + 10$

$= (x + 5)(x + 2)$

2.

X^2-5x+6=

${x}^{2} - 5x + 6 \\ = (x - 6)(x + 1)$

3.X^2+x-2=

${x}^{2} + x - 6 \\ = (x + 3)(x - 2)$

4.X^2-3x=

${x}^{2} - 3x \\ = x(x - 3)$

5.N^2-6n-40=

${n}^{2} - 6n - 40 \\ = (n - 10)(n + 4)$

6.X^2+10x+21=

${x}^{2} + 10x + 21 \\ = (x + 7)(x + 3)$
