Question

If 2 in a zero of the
of the polynomial P(x) = 2x - ² 3x+7a
find the value of a..


​

Answer 1

.

Step-by-step explanation:

P(x) = 2x - ² 3x+7a

given

2 is a zero of the polynomial

P(2)=0

2(2)²-3(2)+7a=0

8-6+7a=0

2+7a=0

7a=-2

a=-2/7

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
