Step-by-step explanation:
Answer: -a2 - 2ab - b2 + 25 =
-1 • (a2 + 2ab + b2 - 25)
Final result :
-a2 - 2ab - b2 + 25
Step-by-step explanation:
Let's solve your equation step-by-step.
x2−4x+3=0
Step 1: Factor left side of equation.
(x−1)(x−3)=0
Step 2: Set factors equal to 0.
x-1=0 or x-3=0
For this one add one on both sides
x−1+1=0+1 x=1
For this one add 3 on both sides
x−3+3=0+3. x=3
x=1 or x=3
