Question

use suitable identity and solve (y²+3/2)(y²-3/2)​

Answer 1

Answer:

Step-by-step explanation:

⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐

⭐ \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

Answer:

see below!

Step-by-step explanation:

(y² + 3/2)(y² - 3/2)

Formula = x² - (a - b)x ab

= y² - (3/2 - 3/2)y 3/2 X 3/2

= y² - 6/4y - 9/4 is your answer.
