Question

factories the following .(1) 5xsqare+20x-15. (2) xsquare yz-xysquare+xyzsquare

Answer 1

I hope my answer is right

Answer 2

ANSWER

$5 {x}^{2} + 20x - 15$

$5( {x}^{2} + 4x - 3) = 0$

$= > {x}^{2} + 4x - 3 = 0$

$= {x}^{2} + 3x - x - 3 = 0$

$= x(x + 3) - 1(x + 3) = 0$

$(x + 3) \: \: \: (x - 1)$

Answer
${x}^{2} yz - x {y}^{2} + xy {z}^{2}$

$xy( {x}^{2} z - y + {z}^{2} )$
