Question

desenvolva os produtos notáveis :

a) (3x+1)^2
b)(5x^3+xy)^2
c)(2x-2)^2
d)(2x-3y)^2
e)(2x^3+5) (2x^3 -5)
f)(6x^3-a) (6x^3+a)​

Answer 1

a) (3x+1)²

(3x + 1)• (3x + 1)

9x² + 3x + 3x + 1

9x² + 6x + 1

b)(5x³+xy)²

(5x³ + xy) • (5x³ + xy)

25x^6 + 5x⁴y + 5x⁴y + x²y²

25x^6 + 10x⁴y + x²y²

c)(2x-2)²

(2x - 2) • (2x - 2)

4x² - 4x - 4x + 4

4x² - 8x + 4

d)(2x-3y)²

(2x - 3y) • (2x - 3y)

4x² - 6xy - 6xy + 9y²

4x² - 12xy + 9y²

e)(2x³+5) (2x³ -5)

4x^6 - 10x³ + 10x³ - 25

4x^6 - 25

f)(6x³ -a) (6x³+a)

36x^6 + 6x³a - 6x³a - a²

36x^6 - a²
