User: Find the quotient. (6x2 - x - 40) ÷ (5 + 2x)

Weegy: (6x^2 - x - 40) ÷ (5 + 2x) = [(3x - 8)(2x + 5)]/(2x + 5) = 3x - 8

User: Factor -2bk2 + 6bk - 2b.

Factor -2bk2 + 6bk - 2b.
Weegy: -2bk^2 + 6bk - 2b = -2b(k^2 - 3k + 1) User: Select the correct difference. -3z7 - (-5z7) 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 the four-term polynomial. pq - 3r + pr - 3q. Weegy: pq - 3r + pr - 3q = (p - 3)(q + r) User: Factor p2 - 8p - 20. Weegy: p^2 - 8p - 20 = P*P - 10p + 2p - 10*2 = (p - 10)(p + 2) (More)

Find the product. (n 8)(n - 2)
Weegy: (n + 8)(n - 2) = n^2 - 2n + 8n - 16; = n^2 + 6n - 16 User: Select the correct difference. 5d2 + 4d - 3 less 2d2 - 3d + 4 Weegy: (5d^2 + 4d - 3) - (2d^2 - 3d + 4) = 3d^2 + 7d - 7 User: Find the greatest common factor of 15x2y3 and -18x3yz Weegy: The greatest common factor of 15x^2y^3 and -18x^3yz is 3x^2y . 15x^2y^3 = 3x^2y*5y^2 -18x^3yz = 3x^2y*(-6xz) User: Choose the product. (5x2 + 2x - 3)(x - 1) User: Find the quotient. (6x2 - x - 40) ÷ (5 + 2x) (More)

(5x^2 + 2x - 3)(x - 1)
= 5x^3 - 5x^2 + 2x^2 - 2x - 3x + 3
= 5x^3 - 3x^2 - 5x + 3

(6x^2 - x - 40) ÷ (5 + 2x)
= (2x + 5)(3x - 8)/(5 + 2x)
= 3x - 8 where x can not be -5/2.
