Step-by-step explanation:

Now we have to multiply

(x+5) (x-3). multiply x with (x-3 ) and +5 with (x-3)

so, = x(x-3) +5(x-3)

= x²-3x + 5x -15

= x²+2x-15 ...........(1)

Now factorise the equation (1)

= x²+5x-3x-15

= (x²+5x) -(3x+15)

Now take x as common in (x²+5x) and 3 in (3x+15) so,

x(x+5) -3(x+5)

(x-3)(x+5) ia the answer
