Solve for x.

xenn [34]

Answer:

$a \: \: x = \frac{ -1 ± i\sqrt{139}}{14}$

Explanation:

Since this is unfactorable, use the Quadratic Formula:

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

Now, take the information and input it:

$-1 ± \frac{ \sqrt{1 - 4(7)(5)}}{2(7)} \\ \\ -1 ± \frac{ \sqrt{ -139}}{ 14} = \frac{-1 ± i\sqrt{139}}{14}$

I am joyous to assist you anytime.

Find the values of x and y if (x+2,y)=(3,4).

gogolik [260]

Answer:

x = 1 and y = 4

Step-by-step explanation:

Solution,

(x+2,y) = (3,4)

Now,

Comparing corresponding elements,

x+2 = 3 , y = 4

or, x = 3 - 2 , y = 4

or, x = 1 , y = 4

Therefore, the value of x is 1 and y is 4.
