Rewrite Equation: Rewrite the equation in standard quadratic form.To solve the quadratic equation, we need to set it to zero by moving all terms to one side.3x−9x2=−10Add 9x2 and subtract 3x from both sides to get:9x2−3x+10=0
Identify Coefficients: Identify the coefficients for the quadratic formula.The quadratic formula is x=2a−b±b2−4ac, where a, b, and c are the coefficients of the quadratic equation ax2+bx+c=0.In our equation, 9x2−3x+10=0, a=9, b=−3, and c=10.
Substitute into Formula: Substitute the coefficients into the quadratic formula.x=2⋅9−(−3)±(−3)2−4⋅9⋅10x=183±9−360x=183±−351
Simplify Square Root: Simplify the expression under the square root. Since the expression under the square root is negative (−351), we have no real solutions. The equation has complex solutions because the discriminant (b2−4ac) is less than zero.
Write Complex Solutions: Write the complex solutions.The complex solutions can be written as:x=183±−351x=183±i351Since none of the answer choices are in the form of a complex number, we have made a mistake. We need to recheck our calculations.
