4x²-5x+8 = 0 is general type of quadratic equation, whereby a = 4, b = -5 and also c= 8.

You are watching: Using the quadratic formula to solve 4x2 – 3x + 9 = 2x + 1, what are the values of x?

x = (-b±√b²-4ac) / 2a is quadratic formula.

Putting offered values in over equation, we have

x = (-(-5)±√(-5)²-4(4)(8) ) / 2(4)

x = (5±√24-128) / 8

x = (5±√-103) / 8

x = (5±√103√-1) / 8 ∴√-1 = i

x = (5±√103i) / 8 i beg your pardon is the carolannpeacock.com.
