Solve for x?

Question

9x^2 - 14x - 4 = 0

Answer 1

You can always find solutions to a quadratic equation (real or complex) if you use the quadratic formula:

x = [-b ± √(b² - 4ac)]/2a

In your problem:
a = 9 (coefficient of the x² term)
b = -14 (coefficient of the x term)
c = -4 (constant term)

Plugging in a, b, and c into the quadratic formula:

x = [-(-14) ± √((-14)² - 4(9)(-4))]/2(9)
=[14 ± √340]/18

So you have two answers:
x = [14 + √340]/18 = 1.802
OR
x = [14 - √340]/18 = -0.247

Answer 2

X = 1

Answer 3

to solve quadratic equation that the first term ( x2 )have a coefficient, you multiply the coefficient with the constant term -4.

determine two number that when you multiply will give the product of the first and last term and when added will give the sum of the middle term.

in this case the equation have no solution.
1.because the sum of all # can not give -14x.
2.maybe there is a mistake with the middle term -14x.
check the number again.i think it should be -16x

the answer is-- not factorable or no solution.
i tried but I'm sure there is no solution to this,good luck

Answer 4

9x^2 - 14x - 4 = 0

We use the quadratic formula.

x = [-b +/- sqrt(b^2 - 4ac)] / [2a]

x = [14 +/- sqrt(340)] / 18
x = [14 +/- 4sqrt(85)] / 18

Since all of our numeric values are even,

x = [7 +/- 2sqrt(85)]/9

So our two answers are:

x = {[7 + 2sqrt(85)]/9 , [7 - 2sqrt(85)]/9}

Answer 5

x = [14 +/- sqrt(196 +144)]/18

= [14 +/- sqrt(340)]/18 = [14 +/- 18.44]/18

x = -0.2466 or 1.8022 (approximately)

Answer 6

x= 1.802171606
x= -0.24661605

Answer 7

1.801 , -0.246
