Explanation: just divide both by two. It won’t always work like this. You can’t always divide something by 2 to get 2. Find a number that will go into the denominator two times and divide the numerator by it also.
Answer:
(1) x (x+ 3) - 4 (x +3) = 0
(2) x = 4 and x = -3
Step-by-step explanation:
given data
equation
(x−4)(x+3)=0
solution
given equation (x−4)(x+3) = 0
equation as a compound statement is
x (x+ 3) - 4 (x +3) = 0
and
two solutions to the equation are
so x (x+ 3) - 4 (x +3) = 0
x- 4 = 0 and x + 3 = 0
x = 4 and x = -3
