Factor completely: 2x3 + 14x2 + 6x + 42

2[(x2 + 3)(x + 7)]
(2x2 + 6)(x + 7)
(x2 + 3)(2x + 14)
2(x3 + 7x2 + 3x + 21)

Based on what i know about mean, this doesn't add up.

Iwant to know what 3g+5h+4g-2h is my teacher is too selfish to tell us

Use the quadratic formula to solve the equation. if necessary, round to the nearest hundredth. x^2 - 23 = 10x a. -1.93, 11.93 b. 1.93, -11.93 c. 1.93, 11.93 d. -1.93, -11.93
