Question

2. Solve x(x-5)=36
lon
*(x-5)-36
*(x-5)=36
Equation
X2-5x = 36
Simplify the expression
x-5x = 36 x? -5x - 36 = 0
Write in standard form
75
Use any methods in solving quadratic
equations to find the solution
x² - 6x - 36=0
X? -5x - 36 = 0
We use factoring
(x-9) (x + 4) = 0
X-9 = 0 or x + 4 = 0
x=9 x=-4
x(x-5)=36
Check whether the obtained values of x
makes the equation x(x-5)=36 true.
If x=9
if x = -4
9(9-5) = 36
-41-4-5)= 36
9(4) = 36
-4(-9) = 36
36 = 36
36 = 36​
