Substitute the values and into the quadratic formulaand solve for. 5 3 solving 4x 2 3x 1 0 by the quadratic formula.
X2 4 3 x 1 3 0.
4x 2 3x 1 0 quadratic formula. 7 4 which is 7 2. X2 3x 1. Where a is mandatory and nonzero.
The middle term is 4x its coefficient is 4. Algebra solve using the quadratic formula 4x 2 3x 1 0 use the quadratic formulato find the solutions. Please to solve a equation like ax bx c 0 enter or replace the coefficients a b and c.
According to the quadratic formula x the solution for ax 2 bx c 0 where a b and c are numbers often called coefficients is given by. To find the roots of the equation 3x 4x 1 0 enter a 3 b 4 and c 1. Subtract 1 3 from both side of the equation.
A b c click to solve the equation. According to the quadratic formula x the solution for ax 2 bx c 0 where a b and c are numbers often called coefficients is given by. Solve quadratic equation using the quadratic formula 2 3 solving x 2 3x 4 0 by the quadratic formula.
A b and c. The name comes from quad meaning square so the biggest clue is that highest power must be a square in other words x2. Divide both sides of the equation by 3 to have 1 as the coefficient of the first term.
Equation at the end of step 1. Only if it can be put in the form ax2 bx c 0 and a is not zero. Trying to factor by splitting the middle term 2 1 factoring 3x 2 4x 1 the first term is 3x 2 its coefficient is 3.
The last term the constant is 1. 3x 2 4x 1 0 step 2. These are all quadratic equations in disguise.
Now the clever bit. Take the coefficient of x which is 4 3 divide by two giving 2 3 and finally square it giving 4 9. X2 4 3 x 1 3.
