Question

(4x-2)^3 by expansions​

Answer 1

Step-by-step explanation:

$(4x - 2) {}^{3}$

we know that

$(a - b) {}^{3} = a {}^{3} - 3a {}^{2} b + 3ab {}^{2} - b {}^{3}$

$(4x - 2) {}^{3} = (4x) {}^{3} - 3(4x) {}^{2} (2) + 3(4x)(2) {}^{2} - (2) {}^{3}$

$= 64x {}^{3} - 96x {}^{2} + 48x - 8$

hope it's helpful for you :)
