Question

x square - 24 x + 143​

Answer 1

Step-by-step explanation:

We use the splitting the middle term method to solve this.

coeffecient of x: 1

and constant term is: 143

so 1*143= 143

Now we need to arrange -24x in such a way that its sum is -24x and product is 143.

so, we can write -13x - 11x here, the sum is -24x and product is 143.

x sq. -13x - 11x + 143

so taking x as common in first terms, and 11 in last 2 terms,

x(x-13) - 11(x-13)

(x-11)(x-13)

THATS THE FACTORISATION

Answer 2

Answer:

(x-11)(x-13)

Step-by-step explanation:

x^2-24x+143

= x^2-11x-13x+143

=x(x-11)-13(x-11)

=(x-11)(x-13)
