Question

factorisation it x2-x(a+b2) + 2ab
​

Answer 1

Answer:

x

2

−x(a+2b)+2ab

=x

2

−xa−2xb+2ab

−xa−2xb+2ab=x(x−a)−2b(x−a)

−xa−2xb+2ab=x(x−a)−2b(x−a)=(x−a)(x−2b)

−xa−2xb+2ab=x(x−a)−2b(x−a)=(x−a)(x−2b)x=2b,x=a

Answer 2

• x² - x (a + 2b) + 2ab
• x² - xa -2xb +2ab
• x(x - a) - 2b(x - a)
• (x - a) (x - 2b)
• x = 2b, x = a
