Answer 1

Respuesta:

Corona :)

Explicación paso a paso:

A)5x2 + 7x + 2 = 0

5x.2+7x+2=0

5x.2+7x=-2

5x+7x=-2/2

12x=-1

x=-1/12

______________________

B) 2x2 + 3x + 1 = 0

2x.2+3x+1=0

2x.2+3x=-1

2x+3x=$-\frac{1}{2}$

5x=$-\frac{1}{2}$

x=$-\frac{1}{2}$ /5

x=$-\frac{1}{10}$

C) -2x2 + 4x + 6 = 0

-2x.2+4x=-6

-2x+4x=-6/2

2x=-3

x=-3/2

x=-1$\frac{1}{2}$
