3x2-7x+4 = (3x-4)(x-1) when factored

It is a quadratic expression and is (3x+2)(x-2) when factored

Area of rectangle: (x+5)(3x-7) = 3x2+8x-35

The following is the answer:

A quadratic equation is an equation where the highest exponent on the variable is 2. For example, the equation, y=2x2+3x-2 is a quadratic equation. The equation y=2x is not quadratic because the highest exponent on x is 1. (If there is no exponent on an x, then the exponent is 1.) The equation, y=x3+3x2-2 is not quadratic because the highest exponent is three. On a graph, a quadratic equation looks like a U or and upside down U. Here are some more example of quadratic equations: y=x2 y=3x2+2x-3 y=x2+5

Set the equation equal to zero. 3x2 - x = -1 3x2 - x + 1 = 0 The equation is quadratic, but can not be factored. Use the quadratic equation.

Yes. (Assuming that -3x2 is the best representation of 3x2 that this browser will allow.)

If you mean 3x2+4x-2 = 0 then it can be solved by means of the quadratic equation formulla

Yes.

It is x = +/- 2 depending on whether the second term in the equation is -12x or +12x.

No.This quadratic cannot be factored. It is "prime"Note that b2-4ac = (-16)2-4(3)(50) = 256-600 < 0 => roots of corresponding function are imaginary.
