Question

Multiply (5х - 2 ) by (5x+З)​

Answer 1

Answer:

         25x^2 +x-6

Solution,

Find

         $(5x - 2 ) * (5x+3)$

According to algebraic identities,

           

              $(x+a)*(x-b)=x^2+x(a-b)-ab$

Here,

              $x=5x\\a=3\\b=2$

∴  $(5x +3 ) * (5x-2) = (5x)^2 +x(3-2) - (2*3)$

=  $25x^2 +x-6$
