x square - 30xy + 29y square factorise
Answers
Answer:
( x - 29y )( x - y )
Step-by-step explanation:
Given polynomial : x^2 - 30xy + 29y^2
Factorization by splitting its middle term : -
= > x^2 - 30xy + 29y^2
Spitting the middle term of the polynomial ( that is 30, numeric co efficient ) in two number such that their product becomes equal to the product of the numeric co efficient of other term( that are 1 { with x^2 } and 29{ with xy }.
So,
30 = 29 + 1, as the product of 29 and 1 is equal to the product of numeric co efficient of other terms,
= > x^2 - 30xy + 29y^2
= > x^2 - ( 29 + 1 )xy + 29y^2
= > x^2 - 29xy - xy + 29y^2
= > x( x - 29y ) - y( x - 29y )
= > ( x - 29y )( x - y )
Hence,
x^2 - 30xy + 29y in factorized ( or product ) from is ( x - 29y )( x - y ) .
QUESTION :
x square - 30xy + 29y square factorise
ANSWER :
we have to factories
the quadratic polynomial
x²-30xy+29y²
so this question can be solved by splitting the middle term method
for that we required the two no. such that there
sum = -30
product = 29
so the two no. are
-29 and -1
as there
product =( -29)(-1)= 29
and
sum = -29+(-1) =-29-1 =-30
so by applying using the splitting the middle term method
we get
x²-30xy+29y²
= x²-29xy-xy+29y²
by taking X in common by first two terms and y in common by last two terms
we get
x²-29xy-xy+29y²
= x(x-29y)-y(x-29y)
now by taking (x-29y) in common we have
x(x-29y)-y(x-29y)
= (x-29y)(x-y)
hence
x²-30xy+29y² = (x-29y)(x-y)
hence the factors of
x²-30xy+29y
are
(x-29y) and (x-y)
