Question

factorise 32x⁴+12x³y -5x²y²

Answer 1

Answer:

x²(4x-y)(8x+5y)

Step-by-step explanation:

32x⁴+12x³y -5x²y²

=x²(32x²+12xy-5y²)

=x²{32x²+(20-8)xy-5y²}

=x²{32x²+20xy-8xy-5y²}

=x²{4x(8x+5y)-y(8x+5y)}

=x²(4x-y)(8x+5y)

Answer 2

Answer:

x²(4x-y)(8x+5y)

LET'S TAKE X² COMMON FROM ALL

• x²[(32x²+(20-8)xy-5y²]
• x²(4x(8x+5y)-y(8x+5y)
• x²(4x-y)(8x+5y)

SO THIS IS THE SOLUTION .

HOPE YOU LIKE IT.
