2. I need help with question in the attached picture!

TiliK225 [7]

Answer:

Option D is correct.

Step-by-step explanation:

2x^2 -4x +9

We need to find root of the equation.

We will use quadratic equation to solve.

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

here a =2, b=-4 and c=9

Putting values and finding the value of x

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\x=\frac{-(-4)\pm\sqrt{(-4)^2-4(2)(9)}}{2(2)}\\x=\frac{4\pm\sqrt{16-72}}{4}\\x=\frac{4\pm\sqrt{-56}}{4}\\x=\frac{4\pm\sqrt{-(2*2*2*7)}}{4}\\x=\frac{4\pm\sqrt{-(2^2*2*7)}}{4}\\x=\frac{4\pm\sqrt{2^2}\sqrt{-14}}{4}\\We\,\,know\,\,\sqrt{-1}=i\,\,\\x=\frac{4\pm2\sqrt{14}i}{4}\\Dividing\,\,by\,\,4\,\,\\x= 1\pm\frac{\sqrt{14}i}{2} \\So,\\x=1+\frac{\sqrt{14}i}{2} \,\,and\,\, x=1-\frac{\sqrt{14}i}{2}$

So, one of the root is $x=1+\frac{\sqrt{14}i}{2}$

So, Option D is correct.

How is the process of multiplying fractions different from the process of adding fractions

Ganezh [65]

In adding fractions i believe you add across and multiplying fractions you have to multiply numerator by denominator!

If that answers your question make sure to mark as brainliest!

kotykmax [81]

Answer:

Step-by-step explanation:

There's no solution because they are not touching each other. If they intersected at one point there would b one solution and if one is exactly on top of another there's infinity solutions which looks like only one line.
