$\left(x^2+4x-23\right)\left(x+5\right)=0$
Learn how to solve equations problems step by step online. Find the roots of (x^2+4x+-23)(x+5). Find the roots of the equation using the Quadratic Formula. Break the equation in 2 factors and set each equal to zero, to obtain. Solve the equation (1). To find the roots of a polynomial of the form ax^2+bx+c we use the quadratic formula, where in this case a=1, b=4 and c=-23. Then substitute the values of the coefficients of the equation in the quadratic formula: \displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}.
