Step-by-step explanation:

$third \: term = ( \frac{1}{2} \times coefficient\: of \:x)^{2} \\ \\ = ( \frac{1}{2} \times \frac{ - 2}{7} )^{2} \\ \\ = ( \frac{ - 1}{7} )^{2} \\ \\ = \frac{1}{49}$

So, you need to add $\frac{1}{49}$ on both sides of the quadratic equation.

Hi!

This question is about math.

$-12(-3) + 7$

$36+7$

$=43$

Explanation: You had to used order of operations on this math problems. Then you can also used P-Parenthesis, E-Exponents, M-Multiply, D-Divide, A-Add, and S-Subtract. ("Please Excuse My Dear Aunt Sally".)

For Example: (65+15*8/2)

$15*\frac{8}{2}=60$
