Question

factorise 2x square - 3 x square - 17 X + 30​

Answer 1

Answer:

(2 - x) (2 + x) (3 - x) (-3 + x) - 17 x + 30

Step-by-step explanation:

2x²-3x²-17x+30

(2x)² - (3x)² - 17x + 30

open the brackets

(2+x)(2-x) - (3+x)(3-x) - 17x + 30

2(2-x) +x(2-x) -3(3-x)+x(3-x) - 17x + 30

4-2x + 2x - x²- 9 + 3x + 3x-x² - 17x + 30

(4-2x) + (2x-x²) - (9+3x) + (3x - x²) - 17x + 30

Factorize

2(2-x) + x(2-x) - 3(3-x) + x(3-x) - 17x + 30

(2 - x) (2 + x) (3 - x) (-3 + x) - 17 x + 30
