1)(8-x)^2= 2)(9+4m)^2= 3)(3a+b)^2= 4)(3y+1)^2= 5)(2k-5c)^2= 6)(t+c)^2= 7)(2k-7b)^2= 8)(9a-3p)^2= 9)(5m-4d)^2= 10)(7x+10y)^2=

Answer 1

Ответ:

1)(8-x)² = 64-16х+х²

2)(9+4m)² =81+72+16m²

3)(3a+b)² = 9a²+6ab+b²

4)(3y+1)² = 9y²+6y+1

5)(2k-5c)² = 4k²-20kc+25c²

6)(t+c)² = t²+2tc+c²

7)(2k-7b)² = 4k²-28kb+49b²

8)(9a-3p)² = 81a²-54ap+9p²

9)(5m-4d)² = 25m²-40md+16d²

10)(7x+10y)² = 49x²+140xy+100y²

Answer 2

It looks like you're asking for the expansion of several squared binomial expressions. I can help you with that:

1. $(8 - x)^2 = 64 - 16x + x^2$
2. $(9 + 4m)^2 = 81 + 72m + 16m^2$
3. $(3a + b)^2 = 9a^2 + 6ab + b^2$
4. $(3y + 1)^2 = 9y^2 + 6y + 1$
5. $(2k - 5c)^2 = 4k^2 - 20kc + 25c^2$
6. $(t + c)^2 = t^2 + 2tc + c^2$
7. $(2k - 7b)^2 = 4k^2 - 28bk + 49b^2$
8. $(9a - 3p)^2 = 81a^2 - 54ap + 9p^2$
9. $(5m - 4d)^2 = 25m^2 - 40md + 16d^2$
10. $(7x + 10y)^2 = 49x^2 + 140xy + 100y^2$

These are the expanded forms of the given squared binomial expressions.
