Question

13. Determine the nature of the roots of the following quadratic equation.
i) (x-2a) (x-2b) = 4ab
ii) 9a?x? - 24abcdx + 16c+d2 = 0. a+0,b=0
iii) 2(a² +b)x² + 2 (A +b) x + 1 = 0
iv) (b + c)x? - (a + b + c)x+ a = 0​

Answer 1

Answer:

1. Here is ur ans for (ii) here, a=9a^2b^2
2. b=_24abcd
3. c=16c^2d^2
4. ⛰️=b^2-4ac
5. (-24abcd)^2-4(9a^2b^2)(16c^2d^2)
6. 576a^2b^2c^2d^2-576a^2b^2c^2d^2
7. =0
8. ⛰️=0
9. The roots are real and unequal
