User: Find the greatest common factor of 15x 2 y 3 and -18x 3 yz.

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). (-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: 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: 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.
may100|Points 2738|

User: Simplify the expression. 2(3y - 7) - 5y(2 - y)

Weegy: 2(3y - 7) - 5y(2 - y)

= (6y - 14) - (10y + 5y^2)

= 5y^2 - 4y - 14


User: Factor 360t + 10t 3 - 120t 2

Weegy: a: 10t(t - 6)(t + 6) then you can factor both 10 and T out of all three because it's a common factor 10t(36+t2-12t), [ [ [ this is because if I was to times everything inside the bracket by 10t then I would have the original equation we started with.This can also be factored even more. (10t)(t-6)(t-6) because (t-6) X (t-6) is the same as (t2-12t+36) Thus the final factored form is (10t)(t-6)(t+6) ] ] ]
