Weegy: -3z^(7)-(-5z^(7))
Multiply -1 by the -5z^(7) inside the parentheses.
-3z^(7)-1*-5z^(7)
Multiply -1 by -5z^(7) to get 5z^(7).
-3z^(7)+5z^(7)
According to the distributive property, for any numbers a, b, and c, a(b+c)=ab+ac and (b+c)a=ba+ca. [ Here, z^(7) is a factor of both -3z^(7) and 5z^(7).
(-3+5)z^(7)
To add integers with different signs, subtract their absolute values and give the result the same sign as the integer with the greater absolute value. In this example, subtract the absolute values of -3 and 5 and give the result the same sign as the integer with the greater absolute value.
(2)z^(7)
Remove the parentheses.
2z^(7) ]
User: Select the correct difference.
-3z 7 - (-5z 7)
Weegy: -3z^(7)-(-5z^(7))
Multiply -1 by the -5z^(7) inside the parentheses.
-3z^(7)-1*-5z^(7)
Multiply -1 by -5z^(7) to get 5z^(7).
-3z^(7)+5z^(7)
According to the distributive property, for any numbers a, b, and c, a(b+c)=ab+ac and (b+c)a=ba+ca. [ Here, z^(7) is a factor of both -3z^(7) and 5z^(7).

Remove the parentheses.
2z^(7) ]
User: Factor 3x 2 - 15x - 42
Weegy: 4. 3(x - 7)(x + 2) is the answer. 3x^2 - 15x - 42 = 3(x - 7)(x + 2)
User: Find the product.
(n + 8)(n - 2)
User: Factor 6x 2 - 17x + 5.
Weegy: Not factorable.
User: Factor 6x 2 - 17x + 5
Weegy: Not factorable.
User: Select the correct difference.
5d 2 + 4d - 3 less 2d 2 - 3d + 4
Weegy: The correct difference of 5d 2 + 4d - 3 less 3d 2 - 2d + 4 is: 5d^2+4d-3-2d^2+3d-4 = 3d^2+7d-7.
User: Factor the four-term polynomial.
pq - 3r + pr - 3q
Weegy: The expression 3r - 6 can be written as r - 2.
User: Simplify the expression.
2(3y - 7) - 5y(2 - y)
Weegy: 2(3y - 7) - 5y(2 ...
