Solve by completing the square: x2+4x+4=0x2+4x+4=0. We immediately recognize the short multiplication formula working in reverse: (x+2)2=x2+4x+4(x+2)2=x2+4x+4. Thus, our problem can be rewritten as (x+2)2=0(x+2)2=0. Since 0=00=0, we get x+2=0x+2=0 and therefor...
Now, contrary to everything we've learned before, we're going to move the constant (that is, the number that isnotwith a variable) over to the other side of the "equals" sign: 4x2− 2x= 5 When solving by completing the square, we'll want thex2to be by itself, so we'll need...
(iii) Complete the square by adding the square of one-half of the coefficient of x to both sides.(iv) Write the left side as a square and simplify the right side.(v) Equate and solve.Example 1 Find the roots of x2 + 10x − 4 = 0 using completing the square method. Answer...
In any quadratic, before you complete the square, you first divide through by the leading coefficient to make it 1. In your case of a2 - 2a - 8 = 0, the leading coefficient is already 1. Now you can complete the square. If the linear coefficient is 2r then you want to make the ...
