How many real solutions does 5x^2+7x+1=0 have? explain your answer.

2

Step-by-step explanation:

The graph of 5x^2+7x+1 crosses the x-axis (x=0) twice, so there are 2 real solutions.

_____

The discriminant is b^2 - 4ac, where a=5, b=7, c=1. Its value is ...

... 7^2 -4·5·1 = 29

This value is greater than 0, indicating there are two (2) real roots. They are ...

... (-7±√29)/10

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
