Question

galera os * é ao quadrado(2)
a) (2×+4)* =
b)(5×+9)* =
c)(13×+20)* =
d)((×-6)* =
e)(5×-8)* =
f)(9×-7)* =
g)(10×*-12)* =
h)(x*-2×*)*
i)(11×-6z)*
​

Answer 1

a) (2×+4)* = 4x² +8x +16

b)(5×+9)* = 25x² +90x +81

c)(13×+20)* = 169x² +520x +400

d)((×-6)* = x² -12x +36

e)(5×-8)* =25x² -80x +64

f)(9×-7)* = 81x² - 126x + 49

g)(10×*-12)* = 100x⁴ - 240x² +144

h)(x*-2×*)* => confusa

i)(11×-6z)*= 121x² - 132xz + 36z²
