Question

1) Calcule:
A) (5-x)²
B) (y-3)²
C) (x-y)²
D) (x-7)²
E) (2х-5)²
F) (6у - 4)²
G) (3x-2y)²
H) (2x-b)²
I) (5x²-1)²
​

Answer 1

Explicação passo-a-passo:

a) (5-x)² = 25-10x+x²

b) (y-3)² = y²-6y+9

c) (x-y)² = x²-2xy+y

d)(x-7)² = x²-14x+49

e) (2x-5)² = 4x²-20x+25

f) (6y-4)² = 36y²-48y+16

g) (3x-2y)² = 9x²-12xy+4y²

h) (2x-b)² = 4x²-4xb-b²

i) (5x²-1)² = 25x⁴-10x²+1

Bom estudo!!!!
