${\tt{\red{\underline{\large{Given}}}}}$

• A polynomial
• X²-15x+54

${\sf{\green{\underline{\large{To\:Find}}}}}$

• Factors of the polynomial
• Relationship between cofficient

${\sf{\pink{\underline{\Large{Explanation}}}}}$

X²-15X+54

• we have to spilt the middle term in such a way that the product become 54 and sum become -15

X²-15X+54

=>X²-9x-6x+54

=>x(x-9)-6(x-9)

=>(x-9) (x-6)

=>x=9,6

Additional Information

Let the zeroes of the polynomial be$\tt\alpha{and}\beta$

Then,

$\rightarrow\tt\alpha{+}\beta{=}\frac{-b}{a}$

&

$\rightarrow\tt\alpha{\times}\beta{=}\frac{c}{a}$

Here,

a=1

b=-15

C=54

☞

$\rightarrow\tt\alpha{+}\beta{=}\dfrac{-(-15)}{1}$

$\rightarrow\tt\alpha{+}\beta{=}\dfrac{Cofficient\:of\:X}{Cofficient\:of\:x^2}=$

&

$\rightarrow\tt\alpha{\times}\beta{=}\dfrac{54}{1}$

$\rightarrow\tt{\large\alpha{\times}\beta{=}\dfrac{Constant\:term}{Cofficient\:of\:x^2}}$

Hence,relation verified
