<p>Its late at night and my brain cant seem to rap my head around this math question off the offical online course. Could someone please help me answer this one. </p>
<p>3(x-7)(x-2)=k </p>
<p>In the equation above, k is a constant. If the roots of this equation are 7 and 2, what is the value of k. </p>
<p>0
2
3
7
14</p>
<p>Only viable answer is A) 0. Any other value would change the roots of the given equation.</p>
<p>The root of an equation, in this type of equation (quadratic equation), means the values of x that would make the equation equal to 0.</p>
<p>You’re given two roots, 7, and 2. Try plugging them in now. They’ll both give you the same value for K: 0.</p>
