√193 or x=
Step-by-step explanation:
Let's solve your equation step-by-step.
x=((−2)(7))(x2)−4x+3
Step 1: Simplify both sides of the equation.
x=−14x2−4x+3
Step 2: Subtract -14x^2-4x+3 from both sides.
x−(−14x2−4x+3)=−14x2−4x+3−(−14x2−4x+3)
14x2+5x−3=0
For this equation: a=14, b=5, c=-3
14x2+5x+−3=0
Step 3: Use quadratic formula with a=14, b=5, c=-3.
x=
−b±√b2−4ac

x=
−(5)±√(5)2−4(14)(−3)
