Solve −3x2 − 4x − 4 = 0. x equals quantity of 2 plus or minus 4i square root of 2 all over 3 x equals quantity of 2 plus or minus 2i square root of 2 all over 3 x equals quantity of negative 2 plus or minus 2i square root of 2 all over 3 x equals quantity of negative 2 plus or minus 4i square root of 2 all over 3

x equals quantity of negative plus or minus square root of all over

Step-by-step explanation:

we have

Rewrite (Multiply by both sides)

The formula to solve a quadratic equation of the form is equal to

in this problem we have

so

substitute

remember that

Simplify

use the power rule  

( a b ) n = a n b n

to distribute the exponent.

apply the product rule to  

3 x 2 y 3 . ( 3 x 2 ) 2 ( y 3 ) 2

apply the product rule to  

3 x 2 . 3 2 ( x 2 ) 2 ( y 3 ) 2

raise  

3

to the power of  

2 . 9 ( x 2 ) 2 ( y 3 ) 2 multiply the exponents in   ( x 2 ) 2

.

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 2 ⋅ 2 ( y 3 ) 2

multiply  

2   by   2 . 9 x 4 ( y 3 ) 2

multiply the exponents in  

( y 3 ) 2 .

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 4 y 3

⋅

2

multiply  

3   by   2 . 9 x 4 y 6
