Question Simplify the expression −x2+4x Evaluate −x(x−4)Apply the distributive property −x×x−(−x×4)Multiply the terms −x2−(−x×4)Use the commutative property to reorder the terms −x2−(−4x)Solution −x2+4x Show Solution Find the roots x1=0,x2=4 Evaluate −x(x−4)To find the roots of the expression,set the expression equal to 0 −x(x−4)=0Change the sign x(x−4)=0Separate the equation into 2 possible cases x=0x−4=0Solve the equation More Steps Evaluate x−4=0Move the constant to the right-hand side and change its sign x=0+4Removing 0 doesn't change the value,so remove it from the expression x=4 x=0x=4Solution x1=0,x2=4 Show Solution
