ANSWERS: (6,0) (0,-4) (9,2)
To solve using completing square method we proceed as follows:
x^2-10x+8=0
x^2-10x=-8
but
c=(b/2)^2
c=(10/2)^2=25
thus we can add this in our expression to get
x^2-10x+25=8+25
factorizing the LHS we get:
(x-5)(x-5)=33
(x-5)^2=33
getting the square roots of both sides we have:
x-5=+/-√33
x=5+/-√33
Answer:
yes
Step-by-step explanation:
To know if x = 5 satisfy the equation or not, you just have to applied it into your equation:
3 (5+1) = 3 * 5 + 3
18 = 18
So x = 5 do satisfy the equation
