Question

4x^2+6x=0

5x^2+10x=0

x^2+4×=7×

x^2+6x+8=0

m^2+10m+21=0

x^2-10x+25=0

por factorizacion porfavor

si no sabes no respondas :))​

Answer 1

Respuesta:

(1)

$4x^{2} +6x = 0\\2x (2x + 3 ) = 0\\x1= 0 \\x2= \frac{ -3 }{2}$

(2)

$5x^{2} + 10x = 0\\5x ( x +2 ) = 0\\x1 = 0\\x2=- 2$

(3)

$x^{2} +4x = 7 x\\x^{2} -3x = 0\\x ( x - 3 ) = 0 \\x1 = 0\\x2= 3$

(4)

$x^{2} + 6x + 8 = 0\\(x + 4)(x +2)\\x1 = -4\\x2 = -2$

(5)

$m^{2} + 10m +21=0 \\(m +7 )( m+3) = 0\\m1 = -7\\m2 = -3$

(6)

$x^{2} - 10x + 25 = 0\\(x -5)(x-5) = 0\\x1= 5\\x2= 5$

Suerte en tu tarea crack :D
