We get: px2+5x+r=k(x-1/2)(x-22)=kx2-23k/2+k/11 (k is some, nonzero number) so p=k and r=k/11 p!=r Obviously there is a mistake in condition, so the factors got to be (x-1/22) and (x-22), and then: px2+5x+r=k(x-1/22)(x-22)=kx2-485k/2+k so p=k and r=k, and p=r.
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
