<p>Okay, I know this is probably really really easy..but here goes. I'm supposed to solve for a, b, and c. Where do I start?
The equation is </p>
<p>3ax^2 + (b+5)x + c -7 = 12x^2 -6x- 9 </p>
<p>thanks for any help :]</p>
<p>Match up the coefficiants of x^2, x, and x^0, so you'd get</p>
<p>3a = 12</p>
<p>b+5 = -6</p>
<p>c-7 = -9</p>
<p>thank you so much!</p>
