Question

if 2 zero of the polynomial f(x)=2xsquare-3x+7a​

Answer 1

Answer:

"a" will be "-2/7".

Step-by-step explanation:

Zero of polynomial = 2

To Find:

The value of "a" = ?

Solution:

On putting "x = 2" in the above given expression, we get

⇒ 2(2)^2-3\times 2+7a=02(2)

2

−3×2+7a=0

⇒ 2\times 4-6+7a=02×4−6+7a=0

⇒ 8-6+7a=08−6+7a=0

⇒ 2+7a=02+7a=0

⇒ 7a=-27a=−2

⇒ a=-\frac{2}{7}a=−

7

2

So that the value of "a" will be "-2/7".

Answer 2

Answer:

2x2-3x+7a=0

x = 2

Step-by-step explanation:

2(2)^2-3*2+7a=0

8-6+7a=0

2+7a=0

7a=-2

a=-2/7

Hope my answer is correct
