Question

Help please thank you!

Answer 1

4x^2 + 16x-2= 5x
Minus 16x over

4x2-2= -11x

Add 11x over

4x^2 +11x -2

Use quadratic formula x= 2.9
I’m not sure here. I tried my best. Hope it helps!

Answer 2

Answer:

$x_1=-2.9\\x_2=0.2$

Step-by-step explanation:

The first step is to move the $5x$ to the left side of the equation and then add the like terms:

$4x^2+16x-2=5x\\\\4x^2+16x-2-5x=0\\\\4x^2+11x-2=0$

Now we can apply the Quadratic formula. This is:

$x=\frac{-b\±\sqrt{b^2-4ac}}{2a}$

In this case we can identify that:

$a=4\\b=11\\c=-2$

Finally, we must substitute these values into the Quadratic formula. Then we get:

$x=\frac{-11\±\sqrt{(11)^2-4(4)(-2)}}{2(4)}$

$x_1=-2.9\\x_2=0.2$
