What can no one help me out with these 4 math problems ?????????

OpenStudy (anonymous):

the first one is 5x^2y^4z^2 – 15x^3y^5z^3 + 20x^2y^5z

OpenStudy (anonymous):

it says Factor each problem completely

OpenStudy (anonymous):

the second problem is 7x^3 – 63xy^2

OpenStudy (anonymous):

\[(5x^{2}\times y^{4} \times z)(3xyz -4y -z)\]

OpenStudy (anonymous):

woops. there should be a negative infront of that 5

OpenStudy (anonymous):

can you help me with the scond problem to

OpenStudy (anonymous):

7x^3 – 63xy^2

OpenStudy (anonymous):

the 3rd one is 3x^2 – 5x – 2

OpenStudy (anonymous):

\[(7x)(x ^{2} - 9y ^{2})\]

OpenStudy (anonymous):

which then becomes

OpenStudy (anonymous):

\[(7x)(x-3y)(x+3y)\]

OpenStudy (anonymous):

the third one

OpenStudy (anonymous):

\[(x-2)(3x+1)\]

OpenStudy (anonymous):

3x^2 – 5x – 2

OpenStudy (anonymous):

and the last one I need help with is 3x^2 + 18x + 27

OpenStudy (anonymous):

can you help me on the last one please ? I need help with is 3x^2 + 18x + 27

OpenStudy (anonymous):

factor out a 3 gives you\[3(x^{2} +6x+9)\] which then gives you\[3(x+3)^{2}\]

OpenStudy (anonymous):

thank you so much mwande03 for all your help
