pls answer very important
pls no fake or spam answers pls pls pls

i will mark as brainliest​

Answer 1

Answer

• y = ± 1/2 , y = -1

Given

• 4y³+4y²-y-1

To Find

• Factorization

Solution

$\sf 4y^3+4y^2-y-1\\\\\implies \sf 4y^2(y+1)-(y+1)\\\\\implies \sf (4y^2-1)(y+1)\\\\\implies \sf 4y^2=1\ \;\; \, \;\; y=-1\\\\\implies \sf y^2=\dfrac{1}{4}\;\;,\;\;y=-1\\\\\implies \bf y=\pm \dfrac{1}{2}\;\;,\;\;y=-1$
