What are the roots of 3x2 + 10 = 4x?

sveticcg [70]

Answer:

Option C is correct.

roots of the given equation , $x =\frac{2\pm i\sqrt{26}}{3}$

Step-by-step explanation:

Given the equation: $3x^2+10 = 4x$

We can write this equation as:

$3x^2-4x + 10 =0$

A quadratic equation is in the form of $ax^2+bx+c =0$ ......[1] where a,b ,c are the coefficient and x is the variable,

the solution of the equation is given by;

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

On comparing given equation with equation [1] we get;

a = 3 , b = -4 and c =10

So, the solution of the given equation is given by;

$x = \frac{-(-4)\pm\sqrt{(-4)^2-4(3)(10)}}{2(3)}$

$x = \frac{4\pm\sqrt{(16-120}}{6} = \frac{4\pm\sqrt{(-104)}}{6} = \frac{4\pm\sqrt{(-4 \times 26)}}{6}$

$x =\frac{4\pm2 \sqrt{(-26)}}{6} = \frac{4\pm2 i\sqrt{26}}{6}$ [∴ $\sqrt{-1} = i$

Simplify:

$x =\frac{2\pm i\sqrt{26}}{3}$

therefore, the roots of the given equation are; $x =\frac{2\pm i\sqrt{26}}{3}$

Evaluate the function for h(1) <br><br> h(x) = |1 – 7x|

daser333 [38]

Answer:

We conclude that:

$h\left(1\right)=6$

Step-by-step explanation:

Given

The function is

$h\left(x\right)\:=\:|1\:-\:7x|$

To determine

h(1) = ?

Given the function

$h\left(x\right)\:=\:|1\:-\:7x|$

substitute x = 1 in the function

$h\left(1\right)=\left|1-7\left(1\right)\right|$

$h(1)=\left|1-7\right|$

$h(1)=\left|-6\right|$

Apply absolute rule: |-a| = a

$h\left(1\right)=6$

Therefore, we conclude that:

$h\left(1\right)=6$
