Question

Write the equation 0.3x 2 + 5x - 7 = 0 in general form and then choose the value of "b."

70
50
5

Answer 1

The answer should be 50 the second option is the correct

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.
