Question

factories by splitting the middle term x²-11×-42​

Answer 1

Answer:

$\large{\boxed{\green{\mathcal{Answer-}}}}$

${x}^{2} - 11x - 42 \\ = {x}^{2} - 14x + 3x - 42 \\ = x(x - 14) + 3(x - 14) \\ = (x - 14)(x + 3)$

THEREFORE THE ZEROES ARE ;

$x = 14 \: \: \: \: \: \: \: \: \: \: \:and \: \: \: \: \: \: \: \: \: \: \: \: x = - 3$

Answer 2

Answer:

Hey mate answer of your question is given below by me....

Step-by-step explanation:

x Square-11 x-42

By splitting the middle term we get....

x square -14x +3x-42

x(x-14) +3 (x-14)

(x+3) (x-14)

(x+3)=0

x= -3

(x-14)=0

x=14

I hope it can help you....

Thanks.....
