Question

Factorise by splitting the middle term:x2+ 6x + 8​

Answer 1

Answer:

hi

Step-by-step explanation:

Given that: x

2

+6x+8

=x

2

+4x+2x+8, (split middle term)

=(x

2

+4x)+(2x+8), (group pair of terms)

=x(x+4)+2(x+4), (factor each binomials)

=(x+4)(x+2), (factor out common factor (x+4)

Hence factors of x

2

+6x+8 are (x+4)(x+2)

Answer 2

Using identity : x² + ( a + b)x + ab = ( x + a ) ( x + b )

x²- 4x - 2x + 8x

2

−4x−2x+8

x(x - 4) - 2(x - 4)x(x−4)−2(x−4)

(x - 2)(x - 4)(x−2)(x−4)

Hope this'll help you.
