God, How many solutions and what kind of solutions? The quadratic equation. Negative three X squared minus five X plus two equals zero Will have. So we need to find what the A, the B and the sea is of This are a is negative. Three b is negative five and see us too. We need to find the ABC because the discriminate says B squared minus for a C. So let's plug in our numbers. So we're gonna have negative five squared minus four times negative three times to, and we're gonna have 25 plus 24 which equals 49. So 49 is greater than zero. And 49 is a perfect square because the square root of 49 is seven. When you have a perfect square and it's greater than zero, that means that you're gonna have to riel rational roots.

God, How many solutions and what kind of solutions? The quadratic equation. Negative three X squared minus five X plus two equals zero Will have. So we need to find what the A, the B and the sea is of This are a is negative. Three b is negative five and see us too. We need to find the ABC because the discriminate says B squared minus for a C. So let's plug in our numbers. So we're gonna have negative five squared minus four times negative three times to, and we're gonna have 25 plus 24 which equals 49. So 49 is greater than zero. And 49 is a perfect square because the square root of 49 is seven. When you have a perfect square and it's greater than zero, that means that you're gonna have to riel rational roots.
