Question

Factorize: - 10a2 -15b2 + 20c2.​

Answer 1

Answer:

10a2= 2×5×a×a

-15b²= -1×3×5×b×b

20c²= 2×2×5×c×c

thus, we can see 5 as a common factor

so, 5(2a²-3b²+4c²)

Answer 2

Answer:

10a² - 15b²+ 20c² = 5 ( 2a²+3b²+4c²)

Step-by-step explanation:

10a²= 2×5×9×9=(5)(2×a×a)

15b²=3×5×b×b=(5)(3×b×b)

20c²= 2×2×5×c×c = (5) (2×2×c×c) 10a²-15b²-20c²=(5)

(2×a×a+3b×2×2×c×c)

=5 (2a²+3b²+⁴4c²)
