Determine the nature of the roots 2x 2+8x+3 0
WebGiven, the quadratic equation is 8x² + 2x - 3 = 0. We have to find whether the equation has real roots or not. A quadratic equation ax² + bx + c = 0 has 2 distinct real roots when the discriminant of the equation is greater than zero. Discriminant = b² - 4ac. Here, a = 8, b = 2 and c = -3. So, b² - 4ac = (2)² - 4 (8) (-3) WebFind the Roots (Zeros) f(x)=x^2-2x+5. Step 1. Set equal to . Step 2. Solve for . Tap for more steps... Use the quadratic formula to find the solutions.
