### To create a trinomial square on the left side of the equation find a value that is equal to the square of half of b b.

**Solve x 2 4x 7 0 by completing the square**. Add 7 to both sides. X 4. Then we need to add b 2 4 to both sides to complete the square.

X 2 4x 7 now the clever bit. Keep x terms on the left and move the constant to the right side by adding it on both sides. B 2 2 1 8 2 b 2 2 1 8 2.

7 4 or 7 1 4 1 the common denominator of the two fractions is 1 adding 7 1 4 1 gives 11 1 so adding to both sides we finally get. X 4x 7 7 0 7. X 2 4 0.

X 2 x 4 0 x 2 x 4 0. X 4x 7 0. I am going to complete the square step by step.

X 2 4. On the right hand side we have. To create a trinomial square on the left side of the equation find a value that is equal to the square of half of b b.

Add to both sides of the equation. 2 2 solving x 2 4x 7 0 by completing the square. Add the term to each side of the equation.

Divide 0 0 by 4 4. Add 4 to both sides. X2 4x 7 0 x 2 4 x 7 0.

Take the coefficient of x which is 4 divide by two giving 2 and finally square it giving 4 add 4 to both sides of the equation. X 2 11 or x 2 11. Take the square root of both sides.

B 2 2 2 2 b 2 2 2 2. 3 2 solving 2x 2 4x 7 0 by completing the square. X 2 0 x 4 0.

To create a trinomial square on the left side of the equation find a value that is equal to the square of half of. X 4x 4 7 4. Solve by completing the square x 2 4x 7 0.

The coefficient of 4x is 4. Let b 4. X 2 4x 4 11.

Solve by completing the square x 2 10x 7 0. Add 7 to both side of the equation. X2 x 4 0 x 2 x 4 0.

Solution by completing the square for. To solve by completing the square x 4x 2 7 2 take the coefficient of x divide it by 2 square it and then add it to both sides of the equation. Eliminate b term with 0 to get.

Add 7 7 to both sides of the equation. X2 4x 7 x 2 4 x 7. X 4x 7 0.

X 4x 7. Divide both sides of the equation by 2 to have 1 as the coefficient of the first term.
