Write Quadratic Equation: Write down the quadratic equation.We have the quadratic equation 6X2+7X+10=0.
Identify Coefficients: Identify the coefficients of the quadratic equation.The coefficients are a=6, b=7, and c=10.
Check Factorization: Check if the quadratic can be factored easily.The quadratic equation 6X2+7X+10 does not factor easily because there are no two integers that multiply to 6×10 (60) and add up to 7. Therefore, we will use the quadratic formula to find the solutions.
Recall Quadratic Formula: Recall the quadratic formula.The quadratic formula is X=2a−b±b2−4ac.
Substitute Coefficients: Substitute the coefficients into the quadratic formula.Substitute a=6, b=7, and c=10 into the formula to get X=2(6)−(7)±(7)2−4(6)(10).
Simplify Square Root: Simplify under the square root.Calculate the discriminant: (7)2−4(6)(10)=49−240=−191.
Negative Discriminant: Since the discriminant is negative, the solutions will be complex numbers.We have X=12−7±−191.
Complex Number Solutions: Write the solutions in terms of complex numbers.The solutions are X=12−7+−191 and X=12−7−−191, which can be written as X=12−7+12191i and X=12−7−12191i.
