Answer 1

Answer 2

It seems like you've provided several mathematical expressions, and I'll help you simplify them:

A) 7(4a-1)² - 3(5y-x)²

To simplify this expression, you'll need to expand the square terms and then combine like terms:

= 7(16a² - 8a + 1) - 3(25y² - 10xy + x²) = 112a² - 56a + 7 - 75y² + 30xy - 3x²

B) -10(1/2b+2)²

To simplify this expression, first simplify the square term:

= -10(1/4b² + 2/b + 4)

Now distribute the -10:

= -10/4b² - 20/b - 40

C) 3(a-1)² + 8a;x

It appears there's a typo in your expression; "8a;x" is not a valid mathematical term. If you meant to multiply, it would be like this:

3(a-1)² * 8ax

To simplify this expression, first expand the square term:

= 3(a² - 2a + 1) * 8ax

Now distribute the 3 and 8ax:

= 24ax(a² - 2a + 1)

D) 9c² - 4 + 6(0-2)²

To simplify this expression, start with the square term:

= 9c² - 4 + 6(-2)²

Now, calculate -2²:

= 9c² - 4 + 6(4)

Finally, multiply 6 by 4:

= 9c² - 4 + 24

E) 10ab - 4(2a-b)² + 6b²

To simplify this expression, expand the square term:

= 10ab - 4(4a² - 4ab + b²) + 6b²

Now distribute the -4:

= 10ab - 16a² + 16ab - 4b² + 6b²

Combine like terms:

= 10ab + 16ab - 16a² - 4b² + 6b²

= 26ab - 16a² + 2b²

So, there you have the simplified forms of each of these expressions.
