Help with MATLAB. i did like input('enter the coefficients of a quadratic equation "Ax2 + Bx + C = 0"') fx=(-B+sqrt(B^2+4*A*C))/(2*A); i just dont know how i can ask the user to input three (A,B,C)? thanks! EXERCISE 6 Ask user to enter the coefficients of a quadratic equation, Ax² + Bx + C = 0, i.e. A, B, and C, and calculate the roots of the equation using the quadratic formula, ., --B+VB? - 4AC 2A
7. Give the formula of avoiding roundoff error to solve each of the fol- lowing problem and compute the numerical values. All the results are approximated to 4 digits with rounding arithmetic. (1).

please answer this question with python. Write a program to solve the quadratic equation ax^2 + bx + c = 0 using the standard quadratic formula x = -b plusminus Squareroot b^2 - 4ac/2a or the alternative formula x = 2c/-b Squareroot b^2 - 4ac. Your program should accept values for the coefficients a, b, and c as input and produce the two roots of the equation as output. Your program should detect when the roots are imaginary, but need...
Question 1 of 8, Step 2 of 2 1/12 Correct Consider the following quadratic equation: y2 - 8y + 1 = 0 Step 2 of 2: Use the discriminant, b2 - 4ac, to determine the number of solutions of the given quadratic equation. Then solve the quadratic equation using the -b + b2 - 4ac formula y = 2a Answer Keypad Select the number and type of solutions. Then, enter the solutions. Previous Step Answer Selecting an option will display...
A quadratic equation is generally represented as, ax^2 + bx + c The root(s) of the above quadratic equation is computed using the following formula, root1 = (-b + sqrt(D))/ 2a root2 = (-b - sqrt(D))/2a Where D is the discriminant of the quadratic equation and is computed as, D = b^2 - 4ac Given the value of D, the roots of a quadratic equation can be categorized as follows, D > 0 : Two distinct real roots D =...
6. Following is a statement of a theorem which can be proven using calculus or precalculus mathematics. For this theorem, a, b, and c are real numbers. Theorem If f is a quadratic function of the form f (x) - ax2 + bx + c and a < 0, then the function f has a maximum value when x -b 2a Using only this theorem, what can be concluded about the functions given by the following formulas? (a) g (x)-8x2...

5. Numerical Integration (15 marks] When a charged particle moves perpendicular to a magnetic field it traces out circles in the plane perpendicular to the magnetic field due to the "Lorentz force". Here we consider a small particle (e.g. dust grain or nanoparticle) with a charge to mass ratio of 1 Coulomb per kg moving perpendicular at speed v1 = 1 m/s to a 1 Tesla magnetic field that points in the z direction. In this case the motion is...
