Question

factor each of the following by factoring out the GCF $2x {}^{7} - 10x {}^{5} + 20x {}^{4}$$6x {}^{8} + 12x {}^{10}$$32x {}^{7} + 24x {}^{4} - 8x {}^{3}$MORE NOTES FOR QUESTION 2$6y - 24 \\ answer = (y - 4)$$3a + 12 \\ anwser = 3(a + 4)$

Answer 1

$4x^3-12x^2+8x=4x\cdot x^2-4x\cdot3x+4x\cdot2=4x(x^2-3x+2)$

For the second one

$50y^6-25y^7=25y^6\cdot2-25y^6\cdot y=25y^6(2-y)$

for the third one

$32x^7+24x^5-8x^3=8x^3\cdot4x^4-8x^3\cdot3x^2-8x^3\cdot1=8x^3(4x^4+3x^2-1)$

The greatest common factor for the first one is 4x

for the second one is 25y^6

and for the third one is 8x^3
