Question

The solution of the equation
x2 + 5x – (a? +a - 6) = 0 is....solve fast a² hai​

Answer 1

Step-by-step explanation:

formula for roots of quadratic

expression ax

2

+bx+c=0 is

=

2a

−b±

b

2

−4ac

So for x

2

+5x−(a

2

+a−6)=

⇒

2

−5±

25+4(a

2

+a−6)

⇒

2

−5±

4a

2

+4a+1

⇒

2

−5

±

(a+1/2)

2

=

2

−5

±(a+1/2)

Answer 2

$formula \: for \: roots \: \\ of \: quadratic \: expression  \\ {ax}^{2} +bx+c=0 is  \\ \\= \frac{−b±b2−4ac}{2a} \\ \\So \: for \:   {x}^{2} +5x−( {a}^{2} +a−6)= \\ \\ ⇒ \frac{−5± \sqrt{25+4( {a}^{2} +a−6)} }{2} \\ \\ ⇒ \frac{ −5±\sqrt{ {4a}^{2} +4a+1} }{2} \\ \\ ⇒ \frac{ - 5}{2} ± \sqrt{ {(a+ \frac{1}{2} )}^{2} } \\ \\ \\ \\ ⇒ \frac{ - 5}{2} \: ± \: (a+ \frac{1}{2} ) \: is \: your \: ans....$
