8-(2x-1)² how can i factor it..??
Answers
Step-by-step explanation:
(2*x-1)^2-(8)=0
Step by step solution :
STEP
1
:
1.1 Evaluate : (2x-1)2 = 4x2-4x+1
Trying to factor by splitting the middle term
1.2 Factoring 4x2-4x-7
The first term is, 4x2 its coefficient is 4 .
The middle term is, -4x its coefficient is -4 .
The last term, "the constant", is -7
Step-1 : Multiply the coefficient of the first term by the constant 4 • -7 = -28
Step-2 : Find two factors of -28 whose sum equals the coefficient of the middle term, which is -4 .
-28 + 1 = -27
-14 + 2 = -12
-7 + 4 = -3
-4 + 7 = 3
-2 + 14 = 12
-1 + 28 = 27
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
