text: solve equations using any solution? 1) x(sq)+x-42=0  2) x(sq)+8x-48=0  3) x(sq)+12x+11=0  4) 10x(sq)+3x=1  5) 3x(sq)+7x-31=0  if you can answer any that would be greatly appreciated! 1= (x+7)(x+6) so x= -7, -6  2=(x+12)(x-4) so x= -12, 4  3= (x+11)(x+1) so x= -11, -1  4= (2x+1)(5x-1) so x= -1/2, 1/5  5= use quadratic formula
