Question

(2x +3) · (2x +3)

(4x² - 5) · (4x² - 5)

(5x³- 2x² ) · (5x³- 2x² )

AYUDA PORFAVOR!!

Answer 1

(2x +3) · (2x +3) = (2x +3)^2
4(x^2)+ 2*2x*3+9 = 4(x^2)+12x+9
----------------------
(4x² - 5) · (4x² - 5)= (4x² - 5)²
16(x^4)- 2*4x² * 5+25
16(x^4)-40 x²+25.
----------------------
(5x³- 2x² ) · (5x³- 2x² ) = (5x³- 2x² ) ²
25(x^6)-2* 5x³ * 2x² + 4(x^4)

25(x^6)- 20 x³x²+ 4(x^4)
