Question

what should be subtracted from x^2-3x^2+2x-4 to get -x^2+3x^3-2x+4​

Answer 1

Answer:

When we sprinkle water on the ground, it is soon absorbed by the soil. This is because water percolates through the soil. The process in which water passes down slowly through the sol is called percolation of water.You can change you particular soil's percolation speed to provide better growing conditions for plants. If the soil drains too quickly, then mix it with loam, compost or even clay to slow percolation. For soil that drains too slowly, add loam, compost or sand.
