Answer:

We can't solve it by extracting square root nor by factoring. In the standard form of quadratic equation Ax² + Bx + C = 0, we can observe that the value of C is 5 and B is 7. If we will solve it by factoring, we need two numbers that the product is 5 and the sum is 7. We can only multiply 1 and 5 to have a product of 5. As we can see that the sum of 1 and 5 is 6 and not 7. Therefore, it's not possible to solve it by extracting the square roots nor by factoring.
