Solve the quadratic equation. Write complex solutions in standard form.x2 – 4x + 13 = 0

Multiply and write the result in standard form.(4 + 7i)(3 + 6i)

Solve the quadratic equation.4×2 + 10x + 2 = 0

Complete the following for the given f(x). (i) Find f(x + h). (ii) Find the difference quotient of f and simplify.f(x) = x2 + 2x

Solve the problem.A rock falls from a tower that is 160 feet high.   As it is falling, its height is given by the formula h=160-16t2 . How many seconds (in tenths) will it take for the rock to hit the ground (h = 0)?

Identify f as being linear, quadratic, or neither. If f is quadratic, identify the leading coefficient.f(x) = 5 + 3×2

Solve the quadratic equation.10×2 = 80x

Use the discriminant to determine the number of real solutions.s2 – 2s – 3 = 0
