Question

Foctorise y²-7x - 60​

Answer 1

Answer:

I think your question is mistake .It should be

X2 -7x -60

=x2 + 12x -5x - 60

= x (x + 12) - 5 (x + 12)

= ( x + 12) ( x - 5) ans

Step-by-step explanation:

first multiply the number 60 × X

than you will get 60 only

than try to multiply any no to get 60 so that we can find the two numbers .so i multiplyed with 12 × 5 = 60 and 12 - 5 = 7

so we got the numbers

than write

X2 + 12x - 5x -60

so now first see

there are two x in the first two numbers so write

x( x+12) - 5(x+12)

than write as their are same number in tge bracket write ( x + 12) ( x - 5)

so by this we get our answer
