Normally you would only solve by completing the square if a is 1 and b is even. But the answer would be half of b. So half of 9 is 4.5 or 4(1/2).
Answer:
Move all terms containing y to the left, all other terms to the right
<u>Add -14y to each side of the equation</u>
<u></u><u></u>
<u></u>
<u>Combine like terms: 5y + -14y = -9y
</u>
<u></u><u></u>
<u></u>
<u>Combine like terms: 14y + -14y = 0
</u>
<u></u><u></u>
<u></u>
<u>Add '20' to each side of the equation</u>
<u></u><u></u>
<u></u>
<u>Combine like terms: -20 + 20 = 0
</u>
<u></u><u></u>
<u></u>
<u>Combine like terms: 7 + 20 = 27
</u>
<u></u><u></u>
<u></u>
<u>Divide each side by -9</u>

Answer:
x=-1
Step-by-step explanation:
x+2-1=0
