22. Which of these quadratic equations has a sum and product of roots equal to -6 and 10?
A. -X2-10x + 6=0
B. 6x2 -10x +6 = 0
C. x2 +6x + 10 = 0
D. x² - 6x + 10 = 0​


Sagot :

Answer:

C. x² + 6x + 10 = 0

Step-by-step explanation:

sum of roots = -b/a = -(-6/1) = 6/1

product of roots = c/a = 10/1

Since the two values are similar fractions, the value of a is 1.

The values of b and c are 6 and 10, respectively.

Substituting these values to the general form of quadratic equation

ax² + bx + c = 0

x² + 6x + 10 = 0

Therefore, the answer is in letter C.
