User: Factor 3y2 - 4y. y(4 - 3y) y(3y - 4) y(4y - 3)

User: Factor 48m - 80n. 16mn(3m - 5n) 16(5n - 3m) 16(3m - 5n)

Weegy: Answer is C) 16(3m - 5n).

Solution
1. Find the lowest common denominator for both numerical coefficient
48= 2.2.2.2.3
80=2.2.2.2. 5
LCD= 2.2.2.2
LCD = 16

2. Perform the operation: 48m - 80n divide both by 16
*48m/16 = 3m
*-80/16 = -5n

3. answer= 16(3m - 5n)




User: Factor x4y2 + x3y3. x3y2(x + 1) x2y2(x + y) x3y2(x + y)

Weegy: The answer is 3x^4y^5.

User: -24a3b3c3 - 84a4b2c factored equals -12a3b2c(2bc2 + 7a). True False

Weegy: True

User: Factor 10x3 + 8x2 - 6x. 2x(5x + 4x - 3) 2x(5x + 4x2- 3) 2x(5x2+ 4x - 3)

Weegy: 10x^3 + 8x^2 - 6x factored would be (c)2x(5x^2+ 4x - 3)

User: Factor 2a5b + 2a4b2 + 2a3b3. 2a2b(a2+ ab2+ ab) 2a3b(a2+ ab + b2) 2ab3(a3+ ab + b2)

Weegy: 2a5b + 2a4b2 + 2a3b3, factors are 2a3b(a2+ ab + b2)

7 - 3[(n^3 + 8n) ÷ (-n) + 9n^2]
= 7 - 3(-n^2 - 8 + 9n^2)
= 7 - 3(8n^2 - 8)
= 7 - 24n^2 + 24
= -24n^2 + 31

5 + 2{x - 4[3x + 7(2 - x)]}

= 5 + 2{x - 4[3x + 14 - 7x]}

= 5 + 2{x - 4[-4x + 14]}

= 5 + 2{x + 16x - 56}

= 5 + 2{17x - 56}

= 5 + 34x - 112

= 34x - 107
