solve by using the quadratic formula
3x^2=11x+4
ANSWER:
General form of a quadratic equation is,
ax^2 + bx + c = 0 ----------------(1)
Given equation is,
3x^2=11x+4
This can be written in the standered form by transforming each term on the right side to left side as follows:
3x^2 - 11x - 4 = 0 -----------------(2)
Compare (1) and (2).... we have,
a = 3 , b = -11 and c = -4
Using quadratic formula, the solution of this equation is given by,
Substitute the values of a, b and c in this formula.... we have,
==> x = ( 11 + 13 )/6 or x = (11 - 13 ) /6
==> x = 24/6 or x = -2/6
==> x = 4 or x = -1/3 , which is the required solution.
Hope you understood.
