Answer:
Complete factorization of 3a²+5a-12 is:
(3a-4)(a+3)
Step-by-step explanation:
We have to factorize the expression:
3a²+5a-12
3a²+5a-12=3a²+9a-4a-12 (by splitting the middle term)
=3a(a+3)-4(a+3)
= (3a-4)(a+3)
⇒ 3a²+5a-12=(3a-4)(a+3)
Hence, Complete factorization of 3a²+5a-12 is:
(3a-4)(a+3)
Answer:
Applying factor polynomials, you will find:
\(3a^2+5a-12=\left(3a-4\right)\left(a+3\right)\)
Step-by-step explanation:
The exercise presents the equation: \(3a^{2} + 5a - 12\).
For factoring an equation, you should write the given equation in factors. Therefore, for solving this exercise, you need to find the factors.
- You should rewrite the equation.
\(3a^2+5a-12= 3a^2-4a+5a-12\)
2. After that, you should break the expression in groups.
\(3a^2-4a+5a-12= (3a^2-4a)+(9a-12)\)
3. Next step, you should factor out each term. For the first factor use a and the second factor use 3.
\((3a^2-4a)+(9a-12)= a(3a-4)+3(3a-4)\)
Here it is possible to see that \((3a-4)\) is a factor common.
4. Finally, factor out \(\left(3a-4\right)\\) in previous expression.
\(\left(3a-4\right)\left(a+3\right)\)
Thus, \(3a^2+5a-12=\left(3a-4\right)\left(a+3\right)\).
