-2 x^2 - 3 x + 2

Result

-2 x^2 - 3 x + 2

Geometric figure

parabola

Alternate forms

-(2 x - 1) (x + 2)

Roots

x = -2

Polynomial discriminant

Δ = 25

Properties as a real function

R (all real numbers)

Derivative

d/dx(-2 x^2 - 3 x + 2) = -4 x - 3

Indefinite integral

integral(2 - 3 x - 2 x^2) dx = -(2 x^3)/3 - (3 x^2)/2 + 2 x + constant

Global maximum

max{ -2 x^2 - 3 x + 2} = 25/8 at x = -3/4

Definite integral

integral_(-2)^(1/2) (2 - 3 x - 2 x^2) dx = 125/24≈5.20833

Definite integral area above the axis between the smallest and largest real roots

integral_(-2)^(1/2) (2 - 3 x - 2 x^2) θ(2 - 3 x - 2 x^2) dx = 125/24≈5.20833

What is x2 in quadratic equation?

A quadratic equation has an x2 (x-squared) term. ("Quadratum" is Latin for square.) The general quadratic equation in standard form looks like. ax2+bx+c=0, . . . . where a≠0.

What is x2 Plus x2?

x squared plus x squared is 2x2.

How do you write 2 cubed?

2 cubed is 23 = 2×2×2 = 8. The term "cube" can be remembered because there are three dimensions in a cube (height, width, and depth) and the number being cubed appears three times in the calculation.

What is 2/3 of a whole number?

To find 2/3 of a whole number we have to multiply the number by 2 and divide it by 3. To find two-thirds of 18, multiply 2/3 x 18/1 to get 36/3. 36/3 is again simplified as 12. Was this answer helpful?

What does the B represent in a quadratic equation?

The b-value is the middle number, the number next to the x. The other letters, a and c, are also numbers like b. Each of these can be any number. In combination, they tell you what the quadratic function will look like when graphed.

What is 2x time 2x?

2x times 2x is 4×2 . In an expression such as 2x, 2 is called the coefficient and x is the variable.

What is x2 minus x2?

Any number minus itself is always zero.

How do you type a cubed symbol?
