Using the quadratic formula to solve 11x^2-4x=1, what are the values of X?

Rashid [163]

The correct answers for x would be $\frac{2 +/- \sqrt{15} }{11}$ .

In order to find this, we must first get the equation to equal 0. In order to do that, subtract 1 from each side to get the following.

11 $x^{2}$ - 4x - 1 = 0

Knowing this we can now use the quadratic equation using a = 11, b = -4 and c = -1. The quadratic equation is below.

$\frac{-b +/- \sqrt{ b^{2} - 4ac} }{2a}$

Now we can plug the values into the equation to solve.

$\frac{4 +/- \sqrt{ -4^{2} - 4(11)(-1)} }{2(11)}$

Then simplify using the order of operations.

$\frac{2 +/- \sqrt{15} }{11}$ .

Solve for x 4(3x – 5) - 2x = -30

german

Answer:

your answer is -1

Step-by-step explanation:

D = distributive property

S = switch

C = combine

I = inverse operations

F = finalize

$4(3x - 5) -2x = -30\\12x -20 -2x = -30\\12x -2x = -30 + 20\\10x = -10\\x = \frac{-10}{10}\\ x = -1$

Well your at 2 and going to -2 so on a number line you be going back or left.

Going two left gets you to zero and going two more get you -2. So in total you went back four and that be represented as -4.
