WebFind the roots of the original quadratic equation. Solution: Since there is no change in the coefficient of x 2 and c, the product of zeroes will remain the same for both equations. Therefore, the product of zeroes (c) = -2 × -15 = … WebSince D < 0, hence this equation has two imaginary solutions. If D = 0, then the solution of the quadratic equation has two real solutions, both being equal. Example: x2+2x+1. D=b2-4ac. D=22-411. D=4-4. D = 0. Since D = 0, hence the equation has …
WebAs sinθ = − 1 2, notice that all four solutions are in the third and fourth quadrants. Example 3.3.3B: Solving a Trigonometric Equation Involving Cosecant Solve the following equation exactly: cscθ = − 2, 0 ≤ θ < 4π. Solution We want all values of θ for which cscθ = − 2 over the interval 0 ≤ θ < 4π. WebNot all quadratic equations are solved by immediately taking the square root. Sometimes we have to isolate the squared term before taking its root. For example, to solve the equation 2x^2+3=131 2x2 +3 = 131 we should first isolate x^2 x2. We do this exactly as we would isolate the x x term in a linear equation.
