what is the discriminant of 3 x squared minus 10 x negative 2 Answer The discriminant of 3 x squared minus 10 x negative 2 is 76 Explanation Given 1 We can find out the discriminant by using the formula So from the equation 1 We have b 10
The discriminant This online calculator calculates the discriminant of the quadratic polynomial as well as higher degree polynomials In algebra the discriminant of a polynomial is a polynomial function of its coefficients which allows deducing some properties of the roots without computing them 1 You are probably aware of the well Step no 1 x2 3x 8 0 x 2 3 x 8 0 take a quadratic equation Step no 2 Compare the equation with standard form ax2 bx c 0 a x 2 b x c 0 to get the values of a b and c Step no 3 Find discriminant b2 4ac 3 2 4 1 8 9 32 41 b 2 4 a c 3 2 4 1 8 9 32 41

Find the Discriminant 3x 2 10x 3x2 10x 3 x 2 10 x The discriminant of a quadratic is the expression inside the radical of the quadratic formula b2 4 ac b 2 4 a c Substitute in the values of a a b b and c c 10 2 4 3 0 10 2 4 3 0 Evaluate the result to find the discriminant For any quadratic equation like a x 2 b x c 0 What is the discriminant The discriminant is the part of the quadratic formula under the square root x b b 2 4 a c 2 a The discriminant can be positive zero or negative and this determines how many solutions there are to the given quadratic equation
a is the coefficient of x 2 b is the coefficient of x c is the constant Cubic Equation The standard discriminant form for the cubic equation ax 3 bx 2 cx d 0 is b 2c 2 4ac 3 4b 3d 27a 2d 2 18abcd Where a is the coefficient of x 3 b is the coefficient of x 2 c is the And then if you did that you would get 3x squared minus 10x plus 3 is equal to 0 times negative 1 which is still equal to 0 So in this case a is equal to 3 b is equal to negative 10 and c is equal to 3 again And we could apply the quadratic formula We get x is equal to negative b b is negative 10
