Question

a)(x+1)la puterea a 2
b)(1+x)la puterea a2
c)(2a+3)la puterea a 2

d)(x-1)la puterea a 2
f)(1-x)la puterea a 2
g)(t la puterea a 2-z la puterea a 2)la puterea a 2

Answer 1

b)(1+x)²=1+2x+x²
c)(2a+3)²=4a²+12a+9

d)(x-1)²=x²-2x+1
f)(1-x)²=1-2x+x²
g)(t ² -z²)²=t⁴- 2*t²z²++z⁴

Formulele care se aplica:

(a+b)²=a²+2ab+b²
(a-b)²=a²-2ab+b²
