Question

  Given : ( r2 - 4r + 4 ) ( 5r2 - 3r - 2 ) From the given expression the factor of  ( 5r2 - 3r - 2 ) are _______________. A( 5r + 1 ) ( r - 2 ) B( 5r + 2 ) ( r - 1 ) C( 5r + 2 ) ( r - 1 ) DNone of these​

Answer 1

Answer:

Given that : $(r^{2} -4r + 4)*(5r^{2} - 3r - 2)$ from the given expression the factor of $(5r^{2} - 3r - 2)$

Required : Find the value of the expression $(5r^{2} - 3r - 2)$

Step-by-step explanation:

Here, $(5r^{2} - 3r - 2)$

that is, $(5r^{2} - 5r + 2r -2)$

that is, $5r(r-1)+2(r-1)$

that is, $(5r+2) (r-1)$

Final Answer : The required final answer is option (B) $(5r+2) (r-1)$
