Question

Q simplify the following: -
(2x - 3y2) (2x +
3y 2)​

Answer 1

Answer:

apply a^2-b^2=(a+b) (a-b)

(2x)^2 -(3y^2)^2

4x^2-9y^4

THIS IS YOUR ANSWER

Answer 2

$\huge{\green{\underline{ \overline</p><p>{\red{ \mid{ \bold{\star{ \blue{ solu}</p><p>{\mathbb{Tion}}{\blue{\star{\red{\mid}}}}}}}}}}}}$

$= (2x - 3 {y}^{2} )(2x + 3y {}^{2} )$

$\because(a - b)( a+ b) = (a - b {)}^{2}$

$\therefore \: = (2x - 3y {}^{2} {)}^{2}$
