User: Factor 3x2 - 15x - 42.

Weegy: 3x^2 - 15x - 42 = 3(x^2 - 5x - 14) = 3(x - 7)(x + 2)

User: Factor 9b2 - 4.

Weegy: 9b^2 - 4
= (3b)^2 - 2^2
= (3b - 2)(3b + 2)

User: Factor k2 + 13k + 12.

Weegy: k^2 + 13k + 12 = (k + 12)(k + 1)

User: Factor 360t + 10t3 - 120t2.

Weegy: 360t + 10t^3 - 120t^2
= 10t(36 + t^2 - 12t)
= 10t(t - 6)^2
= 10t(t - 6)(t - 6)

User: Simplify m - {n + [p - (m + n - p)]}.

m - {n + [p - (m + n - p)]};
= m - {n + (p - m - n + p)};
= m - {n + 2p - m - n}
= m - {2p - m};
= m + m - 2p;
= 2m - 2p
