WebStep 1: If the coefficient a is different from 1, we divide the entire quadratic expression by a to obtain an expression where the quadratic term has a coefficient equal to 1: x^2+bx+c x2 + bx+ c. Step 2: We divide the coefficient of x (the coefficient b) by 2: \left (\frac {b} {2}\right) (2b) Step 3: We square the expression obtained in step 2: Web5. x²+6x+14 by completting the square Answer: x2+6x+14=0. Step 1: Subtract 14 from both sides. x2+6x+14−14=0−14. x2+6x=−14. Step 2: The coefficient of 6x is 6. Let b=6. Then we need to add (b/2)^2=9 to both sides to complete the square. Add 9 to both sides. x2+6x+9=−14+9. x2+6x+9=−5. Step 3: Factor left side. (x+3)2=−5. Step 4 ...

Set the equation equal to zero. Divide 10 by 2 and add the result to both sides. Add a 2 and 10a together. Subtract the 21. Tags: Question 4. WebAs a result we need to take difference. We take 16 from 9 to get -7. So know we know that (x+3)^2-16=x^2+6x-7. We can now use this to solve the equation as we know that it is equal to 0. We must remember that when solving equations, you must do the same to both sides of the equation. So, as follows. (x+3)^2-16=0, add 16 to both sides to get ... the perlstein
