Move to Standard Form: Write the equation in standard form by moving all terms to one side of the equation.4x2+52=−8xAdd 8x to both sides to get:4x2+8x+52=0
Factor or Use Quadratic Formula: Factor the quadratic equation if possible.The quadratic equation 4x2+8x+52 does not factor nicely, so we will use the quadratic formula to find the solutions for x. The quadratic formula is x=2a−b±b2−4ac, where a=4, b=8, and c=52.
Calculate Discriminant: Calculate the discriminant to determine the nature of the roots.The discriminant is given by b2−4ac. Let's calculate it:Discriminant = (8)2−4(4)(52)Discriminant = 64−832Discriminant = −768Since the discriminant is negative, there are no real solutions to the equation, only complex solutions.
Calculate Complex Solutions: Since the discriminant is negative, calculate the complex solutions using the quadratic formula.x=8−8±−768We can simplify −768 as 768⋅i, where i is the imaginary unit.
Simplify Solutions: Simplify the solutions.x=8−8±768⋅ix=8−8±83⋅ix=−1±3⋅i
