factor the expression completely. -14x² + 7x⁴
factor the expression completely. -14x² + 7x⁴
Answer
Explanation:
Step1: Find the greatest common factor (GCF)
The GCF of ( - 14x^{2}) and (7x^{4}) is (7x^{2}). [ -14x^{2}+7x^{4}=7x^{2}(- 2)+7x^{2}(x^{2}) ]
Step2: Factor out the GCF
[ 7x^{2}(-2 + x^{2})=7x^{2}(x^{2}-2) ]
Answer:
(7x^{2}(x^{2}-2))
