Answer 1

I'll help one sec

Answer 2

The general form of a quadratic equation is that which is expressed in a form,
                                     ax² + bx + c = 0 
To write the equation in its general form, eliminate the decimal by multiplying the equation by 10. It now becomes,
                                        3x² + 50x - 70 = 0
The value of b is therefore 50 and the answer is the second choice. 

Hope this Help:)
