Solve the equation 9k2 – 6k = 11 by completing the square.

The solutions of the given equation are and .

Explanation:

The given equation is

Divide both sides by 9.

If an expression is then we need to add in the expression to make it perfect square.

In the above equation , so add on both the sides.

Taking square root both the sides.

Add 1/3 on both the sides.

Therefore the solutions of the given equation are and .

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion
