Question

व्हाट विल बी द आंसर ऑफ फोर बी क्यूब माइनस 6b स्क्वायर प्लस 10 b-15​

Answer 1

Answer:

(2b - 3) (2b² + 5)

Step-by-step explanation:

You need factorization, I suppose.

Now, 4b³ - 6b² + 10b - 15

= 4b³ - 6b² + 10b - 15

= 2b² (2b - 3) + 5 (2b - 3)

= (2b - 3) (2b² + 5)

This is the required factorization.

Note: To factorize any given term, just remember to to see by what value of the variable, the given term becomes zero. Here we see that when b = 3/2, the term is zero and that is why we have taken (2b - 3) being its factor.
