Question

Factorise the following by splitting the middle term (free points+I'll mark as brainliest)

19k²+40kL-59L²

Answer 1

Answer:

Step-by-step explanation:

19K^2+40KL-59L^2

now,

a.b=19x59=1121

now, when we multiply axb we get 1121 and when we subtract we get 40

so find 2 no.s such that axb=1121 and a-b=40

the two no.s are 19 and 59

as 19 x 59 = 1121

and 59-19= 40

so now

19K^2+59KL-19KL-59L^2

so,  19K^2+19KL-59KL-59L^2

now,

19K(K+L) - 59L(K+L)

now, (19K-59L) (K+L)

Answer 2

Answer:

(k-l) (9k+59l)
