Question

ayudaaaaaaaaaaaaaaaaaaa xd porfavor

Answer 1

Respuesta:

1)

X²+6x+8= 0

(x +4)(x+2)= 0

x+4= 0

X1= - 4

X+2= 0

X2= - 2

2)

X² - 2x - 48= 0

(x-8) (x+6)= 0

X- 8= 0

X1= 8.

X+6= 0

X2= - 6.

3)

4x²+8x= 0

4X(x+ 2)= 0

4x= 0

X1= 0/4

X1= 0

X+2= 0

X2= - 2.

4)

X²+3x= 0

X( x +3)= 0

X1= 0

X+3= 0

X2= - 3

5)

X² - 9= 0

X²= 9

X= √9

X1= 3

6)

4x² - 36=0

4X² = 36

X ²= 36/4

X²= 9

X= √9

X1= 3
