Answer 2

$\sf\huge\bold{\underline{\underline{{Solution}}}}$

$\sf \longmapsto {a}^{2} - 3a + 5 - \dfrac{1}{2} (3 {a}^{2} - 5a + 7)$

Taking LCM of the Equation:-

Here,2 is the LCM of the Equation then , multiply 2 with a²-3a+5.

$\sf \longmapsto \dfrac{2( {a}^{2} - 3a + 5) - 1(3 {a}^{2} - 5a + 7) }{2}$

$\sf \longmapsto \dfrac{2 {a}^{2} - 6a + 10 - 3 {a}^{2} + 5a - 7}{2}$

Now ,we take Variable terms together and constant terms together.

$\sf \longmapsto \dfrac{2 {a}^{2} - 3 {a}^{2} - 6a + 5a + 10 - 7 }{2}$

$\sf \longmapsto \dfrac{ - {a}^{2} - a + 3}{2}$

Taking a common

$\sf \longmapsto \dfrac{a( - a - 1 )+ 3}{2}$

$\sf \longmapsto \dfrac{-a( a +1 )+ 3}{2}$
