Factorise the following 1) x²+4x+4
2) x²+7x+12
3) x²-2x+1
4) x⁴-4
5)2x²-50
6)√567893
7) √3467315
8) x-2/3--3/4(x-2)=1-2x

​

Answer 1

Very hard......................

Answer 2

(1).X²-4x+4

=x²-2x-2x+4

=x(x-2)-2(x-2)

=(x-2)(x-2)

=(x-2)²

5.0

(2). x2-7x+12=0

x2-4x-3x+12=0

x(x-4)-3(x-4)=0

(x-4)(x-3)=0

(3).
