factor out the greatest common factor.\n10x² + 20x - 5\n?(2x² + 4x - 1)
Answer
Explanation:
Step1: Find GCF of coefficients
The coefficients are 10, 20, - 5. The GCF of 10, 20 and - 5 is 5.
Step2: Factor out the GCF
We divide each term of the polynomial (10x^{2}+20x - 5) by 5. (\frac{10x^{2}}{5}=2x^{2}), (\frac{20x}{5}=4x), (\frac{-5}{5}=-1). So (10x^{2}+20x - 5 = 5(2x^{2}+4x - 1))
Answer:
5
