Given : Expression $30x^2-5x-10$

To find : Which expressions are equivalent to the following?

Solution :

Write equation as, $30x^2-5x-10$

Re-write expression as $6x^2-x-2$

$6x^2-x-2=6x^2-4x+3x-2$

$=0$

$6x^2-x-2=2x(3x-2)+1(3x-2)$

$6x^2-x-2=(3x-2)(2x+1)$

Therefore, the expression are equivalent is $6x^2-x-2=(3x-2)(2x+1)$
