Question

Factorize: 5 - (3x^2 - 2x)(6 - 3x^2 + 2x)

Answer 1

Answer:

5-{ 18x²-9x⁴+6x³-12x+6x³-4x²}

5-(-9x⁴+12x³+14x²-12x)

9x⁴-12x³-14x²+12x+5

Answer 2

Answer:

Step-by-step explanation:

5 - (3x^2 - 2x)(6 - 3x^2 + 2x)

= 5(-3x^2  + 2x)(6 - 3x^2 + 2x)

= 5(9x^2 + 2x)(6 + 9x^2 + 2x)

= 45x^2 + 10x (6 + 9x^2 + 2x)

= 45x^2 + 60x + 90x^2 + 20x^2

= 155x^2 + 60x
