Question

(y^2+3/2) (y^2-3/2) use suitable identite to find the product class 9th ch- polynomials

Answer 1

$\textbf {Hey there, here is the solution.}$

⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐

⭐$\bigg( y^2 + \dfrac{3}{2} \bigg) \bigg( y^2 - \dfrac{3}{2} \bigg)$

⭐

⭐We know that (a + b) (a - b) = a² - b²:

⭐$= \bigg(y^2 \bigg)^2 -\bigg ( \dfrac{3}{2} \bigg)^2$

⭐$= y^4 -\dfrac{9}{4}$

⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐

Answer 2

$\bf \large \it \: Hey \: User!!!$

given :- (y² + 3/2) (y² - 3/2)

by using 3rd identity a² - b² = ( a + b ) ( a - b )

here a = y² and b = 3/2

( y² + 3/2 ) ( y² - 3/2 ) = (y²)² - (3/2)²

= y⁴ - 9/4
