And we are going to factor 10x squared minus 13x
minus three equals zero. We're going to break this
up into two binomials, and the first term of our binomials are going to be two x and five x. Now we're going to factor
the negative three. So our second terms are going to be negative three and one. So we have two x minus three times five x plus one equals zero. We're going to set each
binomial equal to zero. So we have two x minus three equals zero, or five x plus one equals zero. And so our final answer is going to be x is equal to three over two, or x is equal to negative one over five.
