Use a special factoring formula to factor the expression.

(8s^3)-(125t^3)

Step 1

Formula used:

(a^{3} - b^{3}) = (a - b)(a^{2} + ab + b^{2} )

Step 2

Now we have

8s^{3} - 125t^{3}

Now apply the above formula, we get

8s^{3} - 125t^{3 }= (2s)^{3} - (5t)^{3}

= (2s - 5t)[(2s)^{2} +(2s)(5t)+ (5t)^{2} ]

Step 3

Now simplify the above term, we get

8s3 - 125t3 = (2s - 5t)( 4s...
