Final result :
-1 • (x2 - x + 8)
Step by step solution :
Step 1 :
Raise x to the 2nd power
Exponentiaion :
Equation at the end of step 1 :
(((0-(4•(x2)))+-7x)+-4)+(((3•x2)+8x)+-4)
Step 2 :
Raise x to the 2nd power
Exponentiaion :
Equation at the end of step 2 :
(((0-(4•x2))+-7x)+-4)+(3x2+8x-4)
Step 3 :
Simplify -4x2-7x-4 + 3x2+8x-4
Pulling out like terms :
3.1 Pull out like factors :
-x2 + x - 8 = -1 • (x2 - x + 8)
