Perform the long division (y^3 - 125) ÷ (y - 5) User: Multiply (6z^2 - 4z + 1)(8 - 3z)
Weegy: (6z^2 - 4z + 1)(8 - 3z) = -18z^3 + 60z^2 - 35z + 8 User: Simplify b(a + b) - a(a - b). Weegy: b(a + b) - a(a - b) = ab + b^2 - (a^2 - ab) = ab + b^2 - a^2 + ab = 2ab + b^2 - a^2 (More)

(y^3 - 125)/(y - 5)
= (y - 5)(y^2 + 5y + 25)/(y - 5)
= y^2 + 5y + 25

Simplify 5 + 2{x - 4[3x + 7(2 - x)]}.
Weegy: 5 + 2{x - 4[3x + 7(2 - x)]} = (2x + 32x) + (5 - 112) = 34x - 107 User: Find the product. (7q - 5)(7q + 5) Weegy: (7q - 5)(7q + 5) = 49q^2 + 35q - 35q - 25 = 49q^2 - 25 User: Find the quotient. (35n^3 - 30n^2 + 25n) ÷ (-5n) Weegy: (35n^3 - 30n^2 + 25n) ÷ (-5n) = -7n^2 + 6n - 5 User: Find the product. -2x(x^2 - 3) User: Find the product. -mnp(3m - 5n + 7p) (More)

Factor 9y2 - 12y + 4
Weegy: The factored form of 9y^2 - 12y + 4 is (3y-2)^2 User: The area of a square is found by squaring one of its sides, (A = s2). A certain square has an area of z2 + 18z + 81. Factor the trinomial to find a side of the square Weegy: z^2+18z+81 = (z + 9)^2 User: Factor 64 - x2. Weegy: 64 - x^2 = (8 + x)(8 - x) User: Factor x10 - y2. Weegy: x^10 - y^2 = (x^5 + y)(x^5 - y) User: Factor 0.04m 2 - n 2 Weegy: 0.04m^2 - n^2 = (0.2m - n)(0.2m + n) User: Factor 1 - 2.25x8. User: Factor 4a2 - 25. Weegy: 4a^2 - 25 = (2a + 5)(2a - 5) User: x^2 - 9 (More)
