88 -Apex ;)

The discriminant is 88.

The discriminant is 88 which means that the given quadratic equation has two different solutions for x

It is: 16-20 = -4 which means that the given quadratic expression has no real roots.

If you mean: 4x squared+7x+4 then the discriminant is -15

None because the discriminant of this quadratic equation is less than zero.

B squared -4ac is the discriminant. you get 0, which means it will have one rational solution.

The discriminant is 121.

It can't be solved because its discriminant is less than zero

3x² - 4x + 9 is a polynomial of degree 2.

b2 - 4ac (whatever that 4's sign is it is positive when squared ) (4)2 - 4(2)(- 9) 16 + 72 = 88 ===============Two real roots.

The discriminant is -32.

The derivative of 2x2 + 4x + 8 is 4x+4.

Yes. -4x is one, and 3y is one. They are combined with a "+" sign, and together they are a polynomial.

4x

The degree of this polynomial is 2.

4x(4x^2 + 3x + 1)

d/dx 2x2+3x+7=4x+3

2x2 + (5x-4x)2 + (x-x)2 = 2x2 + x2 + 02 = 2x2 + x2 = 3x2

See definition of polynomial and monomials. You will see.

yes, and it is 14x

2x2-4x-3x+6 2x2-7x+6 (2x+3)(x+2)

2(x^2 +2x + 3)

x^2 + 4x + 5 cannot be factored because its discriminant is less than zero.
