Question

1. (b+5)²
2.(6-c)²
3.(3a-4b)²
4.(6y+3)²
5.(2 1/3+1 2/3b)²
6.(0,02a-0,1b)²

Answer 1

Объяснение:

$1)(b + 5)^{2} = b^{2} + 10b + 25$

$2)(6 - c)^{2} = 36 - 12c + c^{2}$

$3)(3a - 4)^{2} = 9 {a}^{2} - 24a + 16$

$4)(6y + 3)^{2} = 36y^{2} + 36y + 9$

$5)(2 \frac{1}{3} + 1 \frac{2}{3} b) ^{2} = 5 \frac{4}{9} + 7 \frac{7}{9}b + 2 \frac{7}{9} b^{2}$

$6)(0.02a - 0.1b)^{2} = 0.0004 {a}^{2} - 0.004ab + 0.01b^{2}$
