Question

plz complete the math plz i will mark u as brainliest ​

Answer 1

Step-by-step explanation:

GIVEN,

7x²(3x²-5xy+3y²)+12(3x²-5xy+3y²)-9y²(3x²-5xy+3y²)

21x⁴-35x³y+21x²y²+36x²-60xy+36y²-36x²y²+36xy³-27y²

21x⁴+36x²+36y²-27y²-35x³y+21x²y²-36x²y²+36xy³-60xy

57x*6+9y²15x²y²-60x³y⁴ *=power.

base is equal power will add

in taking in x they substracting.

on taking in y they substracting

on xy they are subtraction

3x²(29x⁴+3y²+5y²-30xy⁴)

on taking common table is 3.

y²(29x⁴+3+5-30xy²)

29x⁴+8-30x

X3+8=0

x³=-8

x=√8

x=2√4

• X=2

BECAUSE OF DIVISION of 8
