Which shows the correct substitution of the values a, b, and c from the equation 0 = 4x2 + 2x – 1 into the quadratic formula bel ow? Quadratic formula: x =
2 answers:
Answer:
is the answer.
Step-by-step explanation:
Given quadratic equation is 4x²+ 2x - 1 = 0
To find the solution of the equation we use the quadratic formula
Now we put the values of a = 4, b = 2 and c = (-1)
Therefore, quadratic formula for the equation given will be
0 = 4x²<span> + 2x – 1 this equation is already ordered by degree, so it's in the correct form. the standard form of a parabola is like so: 0 = A</span>x² + Bx - C that's exactly how you plug values into the quadratic formula. the coefficient for your squared value, A, is 4. take the coefficients from your other numbers as well. a = 4 b = 2 c = -1
