The square of factorization 5A plus a plus one

The square of factorization 5A plus a plus one


5a²+a-1
=5(a²+a/5+1/100)-1-1/20
=5[(a+1/10)²-21/4]
=5(a+1/10+√21/2)(a+1/10-√21/2)



A & # - 178; - 5a-36 factorization, quick solution~


Decomposable A & # 178; - 5a-36 = (a + 4) (A-9) by cross phase multiplication



Decomposition factor (a'2 + 5a)'2-12 (a'2 + 5a) + 36


The original formula = (A & # 178; + 5a-6) &# 178;
=(a+6)²(a-1)²
