Answer:
10x2 + 15y2 = (2 × 5 × x × x) + (3 × 5 × y × y) Taking out the common factor 5 we have 10x2 + 15y2 = 5(2x2 + 3y2)

Answer:
Your answer is 5(2x²-3y²+4z²)
Step-by-step explanation:
10x²-15y²+20z²
= 10x² = 2*5*x*x
-15y²= -3*5*y*y
and 20z² = 2*2*5*z*z
- In all terms 5 is common factors
=5( 2*x*x-3 *y*y+2*2*z*z)
=5(2x²-3y²+4z²)
