: can you assist me with the following problems.
simplfy x(4x2+3x-5)-2(4-x2)
evaluate: (g-6h)(g+6h)
factor: 4k2+20k+25k
factor 4g from :8h2j-12g3hj
thank you This question is from textbook

You can put this solution on YOUR website!
simplfy x(4x^2+3x-5)-2(4-x^2)
= 4x^3+3x^2-5x-8+2x^2
= 4x^3+5x^2-5x-8
---------------------
evaluate: (g-6h)(g+6h)
= g^2-(6h)^2
= g^2-36h^2
---------------
factor: 4k^2+20k+25k
= 4k^2+45k
= k(4k+45)
--------------
factor 4g from :8h^2j-12g^3hj
= 4g [(2h^2j/g) - 3g^2h]
----------------
