Answer 1

Answer:

(i) 4x^3y2 ( 3y^2 - x^2)

(ii) 4x( x - 2 ) +3

Step-by-step explanation:

(i) 12 x^3y^4 - 4 x^5y^2

= 4x^3y2 ( 3y^2 - x^2)

(ii) 4x^2 - 8x + 3

= 4x( x - 2 ) +3

Answer 2

Step-by-step explanation:

1)Given expression is 12x³y⁴-4x⁵y²

it can be written as

(4×3×x³×y²×y²)-(4×x³×x²×y²)

=>4x³y²(3y²-x²)

12x³y⁴-4x⁵y²=4x³y²(3y²-x²)

or

it can be also written as

4x³y²[(√3y)²-x²]

it is in the form of a²-b²

a²-b²=(a+b)(a-b)

4x³y²(√3y+x)(√3y-x)

2)Given expression is 4x²-8x+3

=>4x²-2x-6x+3

=>2x(2x-1)-3(2x-1)

=>(2x-1)(2x-3)

4x²-8x+3=(2x-1)(2x-3)
