In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data
3/4(8x + 20) - 4x > -11
x ==> ?
Step 02:
Inequality :
2x + 15 > -11
2x + 15 - 15 > -11 - 15
2x > - 26
2x / 2 > -26 / 2
x > - 13
The answer is:
x > -13

Answer:
see explanation
Step-by-step explanation:
Given
x² - 2x - 4 = 0 ( add 4 to both sides )
x² - 2x = 4
To solve use the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 1)x + 1 = 4 + 1
(x - 1)² = 5 ( take the square root of both sides )
x - 1 = ± ( add 1 to both sides )
x = 1 ± , thus
x = 1 + or x = 1 -
