Polynomial equations have the form P (X) = 0, where P is a polynomial. Linear equations have the form a (x) + b = 0, where a is a linear function and b is a vector. To solve them, one uses algorithmic or geometric techniques, coming from linear algebra or mathematical analysis. Changing the domain of a function can change the problem considerably.
When piecing the backing of a quilt, avoid using a center seam. When a quilt is folded in half, the extra bulk of the center seam along the fold line stresses the quilt, causing the quilt top and batting to break down. Instead, cut one of the lengths of backing fabric into two long, narrow pieces. Stitch a narrow piece to each side of the full-width piece. The quilt should be loaded into the quilting frame with the seams running the same direction as the rail does (also called the belly bar) .
Make sure the quilt is pushed all the way into the binding, but just barely. Let it ride in there easily, not pulled tight or stretched to one side or the other. Sew the binding on along the first edge of the quilt, sewing all the way to the bottom edge. Backstitch and clip your threads. Check the back-the bottom stitching should look nearly the same as the top. Remove the quilt from the machine.
