Question Factor the expression 2(5+r) Evaluate 10+2rSolution 2(5+r) Show Solution Find the roots r=−5 Evaluate 10+2rTo find the roots of the expression,set the expression equal to 0 10+2r=0Move the constant to the right-hand side and change its sign 2r=0−10Removing 0 doesn't change the value,so remove it from the expression 2r=−10Divide both sides 22r=2−10Divide the numbers r=2−10Solution More Steps Evaluate 2−10Reduce the numbers 1−5Calculate −5 r=−5 Show Solution
