Which method is most efficient method to use to solve 2x^2+4x-7=0

Use the quadratic formula

Step-by-step explanation:

Use the quadratic formula

For a quadratic function of the form:

Where a, b and c are the real coefficients of the polynomial

Then, for

The solutions are:

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
