Answer» Answer: \underline{\textsf{Given:}} Given:
\mathsf{\dfrac{x+1}{x-1}-\dfrac{x-1}{x+1}=\dfrac{5}{6}} x−1 x+1
− x+1 x−1
= 6 5
\underline{\textsf{To find:}} To find:
\textsf{Factors of}Factors of \mathsf{\dfrac{x+1}{x-1}-\dfrac{x-1}{x+1}=\dfrac{5}{6}} x−1 x+1
− x+1 x−1
= 6 5
\underline{\textsf{Solution:}} Solution:
\textsf{Consider,}Consider, \mathsf{\dfrac{x+1}{x-1}-\dfrac{x-1}{x+1}=\dfrac{5}{6}} x−1 x+1
− x+1 x−1
= 6 5
\mathsf{\dfrac{(x+1)^2-(x-1)^2}{(x-1)(x+1)}=\dfrac{5}{6}} (x−1)(x+1) (x+1) 2 −(x−1) 2
= 6 5
\mathsf{\dfrac{(x+1)^2-(x-1)^2}{x^2-1}=\dfrac{5}{6}} x 2 −1 (x+1) 2 −(x−1) 2
= 6 5
\mathsf{\dfrac{(x^2+1+2x)-(x^2+1-2x)}{x^2-1}=\dfrac{5}{6}} x 2 −1 (x 2 +1+2x)−(x 2 +1−2x)
= 6 5
\mathsf{\dfrac{4X}{x^2-1}=\dfrac{5}{6}} x 2 −1 4x
= 6 5
\mathsf{6(4x)=5(x^2-1)}6(4x)=5(x 2 −1) \mathsf{24x=5x^2-5}24x=5x 2 −5 \mathsf{5x^2-24x-5=0}5x 2 −24x−5=0 \mathsf{5x^2-25x+x-5=0}5x 2 −25x+x−5=0 \mathsf{5x(x-5)+1(x-5)=0}5x(x−5)+1(x−5)=0 \mathsf{(5x+1)(x-5)=0}(5x+1)(x−5)=0 \implies\boxed{\mathsf{x=5,\dfrac{-1}{5}}}⟹ x=5, 5 −1
\underline{\textsf{Answer:}} Answer:
\textsf{The factors are (5x+1) and (x-5)}The factors are (5x+1) and (x-5) Find more: 1.x^2-(a-1/a)x+1 factorise the following 2.Factorise x^4-(x-z)^4 3.a^4+b^4-7a^2b^2 factorise 4.Factorise the term p^4-256 5.Factorise a^3b^3-9a^2b^2+20ab hey mate its urgent please SOLVE this it is very urgent |
