Answer:
4, 2
Explanation:
Given:
k^2 + 6k +8
To find:
Factorise this.
Let us solve by mid term factor.
Here, 8*1 = 8 and 4*2 = 8 and 4+2 = 6
Hence,
- k² + 4k+2k + 8(Take k common in first two terms and 2 common in last two terms)
- k(k+4) +2(k+4)( Take (k+4) common)
- (k+4)(k+2)
Here clearly a = 4 and b = 2
