Letters that can stand for numbers. When we substitute a specific value for each variable and then perform the operation, it's called evaluating the expression
For Example: Let's evaluate the expression
3y + 2y when 5 = y.
Answer:
X=6,x=2
Step-by-step explanation:
X2-8x+12
So we will have to factorise
So let's solve
X2-8x+12
X2-6x-2x+12
X(x-6)-2(x-6)
(X-2)(x-6)
X-2=0
X=2
X-6=0
X=6
X=6 or x=2
