Question

Hello solve the full solution

Answer 1

10) { (x-1)(x-2)(x² - 9x +14)}/{((x-7)(x² - 3x +2)}
={(x-1)(x-2)(x²-7x - 2x +14)}/{(x-7)(x² - x-2x+2)}
=[(x-1)(x-2){x(x-7) - 2(x-7)}]/[(x-7){x(x-1) - 2(x-2)}]
= (x-1)(x-2)(x-7)/{(x-1)(x-2)(x-7)} =1
Hope this is ur required answer.

9) 100 - a² - b²- 2ab
= 10² - (a²+ b² +2ab)
=10² - (a+b) ² = (10+a+b)(10-a-b)__answer__
Hope this is ur required answer
