Question

factorise by splitting middle term = x²-x²-x-90 ​

Answer 1

Step-by-step explanation:

we have the given expression as;

x² - x - 90

we need to factorise it.

let's use middle term splitting.

now,

=> x²-x-90

=> x²-10x+9x-90

=> x(x-10)+9(x-10)

=> (x-10)(x+9)

thus ,it's factorised.

thank you.

I hope it helps you..
