What is the coefficient of x2 in the expansion of(x+2)3

Pachacha [2.7K]

First expand:

$(x+2)(x+2)(x+2)$

$(x^2+4x+4)(x+2)$

$(x^3+2x^2+4x^2+8x+4x+8)$

Now combine like terms:

$x^3+6x^2+12x+8$

A coefficient is a number that is in front of an x. The number in front of the x squared term is 6.

So the answer is 6.

$15. 7x^{4} - 5x^{4} = 2x^{4} \\17. 6b + 7b - 10 = 13b - 10\\19. y + 4 + 3 ( y + 2 ) = y + 4 + 3y + 6 = 4y + 10\\21. 3y^{2} + 3 ( 4y^{2} - 2 ) = 3y^{2} + 12y^{2} - 6 = 15y^{2} - 6\\23. 0.5 ( x^{4} - 3 ) + 12 = 0.5x^{4} - 1.5 + 12 = 0.5x^{4} + 10.5$
