Question

(7-X)^2= (3b-1)^2= (4a+5b)^2= (3m-4)^2= (2x+7y)^2= (10x^2-8y)^2=

Answer 1

Ответ:

Объяснение:

(7-X)²=  49-14x+x²

(3b-1)²= 9b²-6b+1

(4a+5b)²= 16a²+40ab+25b²

(3m-4)²= 9m²-24m+16

(2x+7y)²= 4x²+28xy+49y²

(10x²-8y)²=100x^4-160x²y+64y²

Answer 3

It looks like you've provided a list of equations, each representing the square of a certain expression. If you'd like, I can help you simplify these expressions or solve for the variables involved. Let's go through each equation one by one:

1. (7-X)^2: Expanding this expression gives you:
   $(7 - X)^2 = 49 - 14X + X^2$

2. (3b-1)^2: Expanding this expression gives you:
   $(3b - 1)^2 = 9b^2 - 6b + 1$

3. (4a+5b)^2: Expanding this expression gives you:
   $(4a + 5b)^2 = 16a^2 + 40ab + 25b^2$

4. (3m-4)^2: Expanding this expression gives you:
   $(3m - 4)^2 = 9m^2 - 24m + 16$

5. (2x+7y)^2: Expanding this expression gives you:
   $(2x + 7y)^2 = 4x^2 + 28xy + 49y^2$

6. (10x^2-8y)^2: Expanding this expression gives you:
   $(10x^2 - 8y)^2 = 100x^4 - 160x^2y + 64y^2$
