Factorise 7√2x 2 -10x-4√2 |
|
Answer» : The factorized form of the given polynomial is : {7√(2)x + 4}{x - √(2)}Given : The quadratic polynomial is : 7√(2)x² - 10X -4√(2)To Find : The factorised form of the given polynomial :7√(2)x ² - 10x -4√(2)Solution : 7√(2)x² - 10x - 4√(2)= 7√(2)x² - 14x+ 4X - 4√(2)= 7√(2)x{x - √(2)} + 4{x - √(2)} = {7√(2)x + 4}{x - √(2)} __________________If it WOULD give to find the zeroes of this polynomial then : 7√(2)x + 4 = 0 and x -√(2) = 0⇒x = -4/{7√(2)} and ⇒x = √(2)⇒x = -4×√2/(7×2) and ⇒x = √(2)⇒x = -4√2/14 and ⇒x = √(2)⇒x = -2√2/7 and ⇒x = √(2) |
