Question

Factorise: x2

+ 6x + 8​

Answer 1

Answer:

x^2+6x+8

=x^2+2x+4x+8

=x(x+2)+4(x+2)

=(x+2)(x+4)

Answer 2

Factorise

x² + 6x + 8

= x² + 4x + 2x + 8

= x(x+4) +2(x+4)

= (x+2) (x+4)

x + 2 = 0. x + 4 = 0

x = 0 - 2 x = = 0 - 4

x = (-2) x = (-4)

Easy Rules to Factorise

• First multiple the first number with last number i.e

x² X. 8 = 8x²

• Split the middle term in such a way that the number after splitting = 6x by adding numbers and = 8x² by multiple same numbers

i.e 4x * 2x = 8x²

4x + 2x = 6x

• Then Calculate or find out common in first two numbers and last two numbers ...
