How do you simplify # -x(1-x)+x(1+7x)#?

Answer 1

#8x^2#

the equation has same #x# so that equation could be = #x(x-1)+x(7x+1)# = #x(x-1+7x+1)# = #8x^2#

To simplify ( -x(1-x) + x(1+7x) ), distribute the ( -x ) and ( x ) terms separately, then combine like terms: [ -x(1-x) + x(1+7x) = -x + x^2 + x + 7x^2 = -x + x + x^2 + 7x^2 = 8x^2 ]

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
