document.write( "This is a quadratic equation (because of the  term). So we want a zero on one side (which we already have) and then we either factor the other side or use the Quadratic Formula. I prefer factoring when possible and this equation factors fairly easily. As a trinomial with a 1 in front of the squared term, this can be factored by answering the question: \"What factors of the number at the end (-8) that add up to the coefficient in the middle (-7)?\" With a little thought and perhaps some trial and error, we should find that the only pair of factors of -8 that add up to -7 are: -8 and 1. So the equation factors into:
