Question

simplify:- (x^2+5x+6)+(a^2-b^2)​

Answer 1

Step-by-step explanation:

Given equation is: x2−5x+6=0

Here, a+b=5;ab=6

a2−b2=(a+b)(a−b)

=(a+b)(a+b)2−4ab

=5.52−4×6

=5.(±1)=±5

Answer 2

Given equation is: x2−5x+6=0

Here, a+b=5;ab=6

a2−b2=(a+b)(a−b)

=(a+b)(a+b)2−4ab

=5.52−4×6

=5.(±1)=±5
