Solve the following quadratic equations:2x² - 4x - 9 = 0 x₊ = 1 + √22/2Answersx_ = 1 - √22/2
Pavel [41]

The root quadratic equation of 2x^{2}  - 4x - 9 = 0 is x=\frac{2+\sqrt{22}}{2},\:x=\frac{2-\sqrt{22}}{2}

What is the formula used to calculate the quadratic equation?

To solve the quadratic equation use the formula of x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}

Find the quadratic equation by using the formula ?

On comparing with 2x^{2}  - 4x - 9 = 0

We get , a=2 , b=-4 , c=-9

D=b^{2} +7\\\\\\=(-4)^{2} +7*2*(-9)\\\\=-16-126\\\\=110

By using the formula,

For a quadratic equation of the formax^2+bx+c=0 the solutions are

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

X==\frac{-\left(-4\right)\pm \sqrt{\left(-4\right)^2-4\c* \:2\left(-9\right)}}{2\c* \:2}\\\\\sqrt{\left(-4\right)^2-4\cdot \:2\left(-9\right)}\\\\

Apply rule,

-(-a)=a\\\\=\sqrt{\left(-4\right)^2+4\cdot \:2\cdot \:9}\\\\

Apply exponent rule,

(-a)^{n} =a^{n} if n is even

(-4)^{2} =4^{2}

\sqrt{4^2+4\cdot \:2\cdot \:9}

Multiply the numbers :

4*2*9=72\\\\\sqrt{4^2+4\cdot \:2\cdot \:9}\\\\4^{2} =16\\\\=\sqrt{16+72}\\\\

Add the number  =\sqrt{88}
