x²-3x-14x+42=0

x(x-3)-14(x-3)=0

(x-14)(x-3)=0

(x-14)=0 and (x-3)=0

x=14 and x=3

please mark me brainliest so i can help other

I always mark brainliest to each answer

SO I EXCEPT YOU TO MARK BRAINLIEST FOR EACH ANSWER NO MATTER THAT YOU WILL MARK ME BRAINLIEST OR NOT

Answer 2

Answer:

hey! mate your answer is here

Step-by-step explanation:

x^2 - 17x + 42 (by middle term splitting method )

we have to split 17 into two such terms that their product is equal to 42 and sum is equal to 17 .

=> x^2 - 17x + 42

=> x^2 - 14x - 3x + 42

=> x( x - 14 ) -3 ( x - 14 )

=> ( x - 14 )( x - 3 ).

so if got understand , please mark it as brainliest answer .
