Question

Factorize : 2x² + y² +82
2x + y² + 87² - 25 e xy thuayz
+- 9х2

Answer 1

Step-by-step explanation:

(-√2x+y+2√2z)^2

Step-by-step explanation:

2x² + y² 8z² - 2√2 xy +4√2yz- 8xz

=>(-√2x)^2+(y)^2+(2√2z)^2+2*(-√2x)*y+2*(y)*(2√2z)

+2*(2√2z)*(-√2x)

=>(-√2x+y+2√2z)^2

We get our this result as per the following formula-

{(x + y + z)}^{2} = {x }^{2} + {y}^{2} + {z}^{2} + 2xy + 2yz + 2zx(x+y+z)

Answer 2

Answer:

i th8nk u may rite this but first confirm .Rewrite 27 as 33 . Since both terms are perfect cubes, factor using the difference of cubes formula, a3−b3=(a−b)(a2+ab+b2) a 3 - b 3 = ( a - b ) ( a 2 + a b + b 2 ) where a=x and b=3 .
