he said. Today we're solving for the someone product of the roots without actually solving the equation. So let's just get right to We have five x Square plus two x minus 10. The equal zero. All right, so we begin. We know that are some is just taking the coefficients in the ratio of minus B over a. And the product is taking the coefficients in the ratio of just seeded by day. They're just identifying coefficients, and we'd be finished. We have that. My B would be too. So we have a minus two in the numerator and a is just five. And then for a product we have, that sea is going to be a minus 10 on again. There's still five, so just simple. Fine. We have minus 2/5 and we have the minus two
