WebA "root" is when y is zero: 2x+1 = 0. Subtract 1 from both sides: 2x = −1. Divide both sides by 2: x = −1/2. And that is the solution: x = −1/2. (You can also see this on the graph) We can also solve Quadratic Polynomials … WebCheck whether the solutions are real or imaginary? Answer: For getting proper understanding we have to follow following steps 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 Δ

WebFirst we need to identify the values for a, b, and c (the coefficients). First step, make sure the equation is in the format from above, ax^2 + bx + c = 0 ax2 +bx +c = 0: x^2+4x-21=0 x2 + 4x − 21 = 0 a a is the coefficient in front of x^2 x2 , so here a = 1 a = 1 (note that a a can’t equal 0 0 -- the x^2 x2 is what makes it a quadratic). b b WebCompleting the square method is a technique for find the solutions of a quadratic equation of the form ax^2 + bx + c = 0. This method involves completing the square of the … nut and fudge
