Question

15. factorise: (x^2+7x+10) =(x+2)​

Answer 1

Answer:

lim

lim

x2 – 7x + 10

— 2

(x - 5)(x 2)

X - 2

When we evaluate the limit we look at the behaviour as x approaches 2 and we are not interested in what happens when x = 2 so we can cancel the (x - 2) factor as x + 2

... lim

:: lim x 2

.. lim

7x + 10

lim (r – 5)
