Question

9. If 2 is a zero of the Polynomial P(x)=2x²-3x-7a find the value of "a" ?
​

Answer 1

Answer:

p(x) = 2x² - 3x - 7a

p(2) = 2(2)² - 3(2) - 7a = 0

2(4) - 6 - 7a = 0

8 - 6 - 7a = 0

2 - 7a = 0

- 7a = -2

a = -2/-7

a = 2/7 Ans

Answer 2

Answer:

$\huge{\fcolorbox{brown}{lightblue}{Answer:}}$

Given that 2 is a zero of

p(x) = 2x²-3x±7a

(i. e) p(2) = 0

⟹2(2)²-3(2) ± 7a = 0

⟹8-6±7a = 0

⟹2±7a = 0

⟹7a = -2

⟹a=-2/7
