The formula in getting the discriminant is b? - 4ac.
2. The factors of 6 is 1 and 6 only.
3. When the discriminant is zero, then the roots are real numbers and equal.
4. We use zero product property in factoring to get the solution.
5. 7x² + 49 = 0 is a quadratic equation where the linear term is undefined
6. When, *2 =9, the solution is x=3.
7. In perfect square trinomial, you need to get first the factors of the constant term.
8. In getting the standard for quadratic equation, you need to arrange first the terms.
9. x² = 25, can be solved easily by using quadratic formula.
10. The solutions of any quadratic equation ax? +bx+c=0 can be determined us

Explanation:
1. The formula of getting a discriminant is b²-4ac because discriminant tells us whether there are two solutions, one solution, or no solutions.
2. Yes, because if you factor any number by 1 it will remain the same
3. if the discriminant is zero, then the roots are real numbers and equal.
Other type of discriminant:
if the discriminant is less than zero, then there are no solution.
if the discriminant is higher than zero, then there are two real roots.
4. We use zero product property in factoring because it help us find two expression that multiply to zero.
Undefined:
5. Yes its undefined because the root is only negative: 7x²+49=0 > 7x²=-49 > x=-7 so there is no real roots or its undefined
Factoring:
6. Yes x=3 is the solution of x²=9 because the square root of 9 is 3: 3•3=9
7-8. Yes
9. No, the easiest way to get the roots of x²=25 is by factoring it
10. *its incomplete*
Ang answer po ay nasa taas... sana po makatulong pa heart nalang din hehe
