How do you solve the equation #(x- 10)(x+ 5)= 0#?

Answer 1

Julia Adams

#x=-5" or "x=10#

#"using the principal that if "#

#axxb=0#

#"then "a=0" or "b=0" or "a=0,b=0#

#"here we have a product of factors equal to zero"#

#"equate each factor to zero and solve for x"#

#x+5=0rArrx=-5#

#x-10=0rArrx=10#

Eva Adamson

To solve the equation (x - 10)(x + 5) = 0, you set each factor equal to zero and solve for x. So, x - 10 = 0 or x + 5 = 0. Solving each equation, you get x = 10 or x = -5. These are the solutions to the equation.

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.
