X^2-8x+21
=x^2-2(4)(x) +16+5
=(x-4)^2+5
here a=1
h=4
k=5
Answer:
4
Step-by-step explanation:
In similar triangles, corresponding angles will be in the same ratio
EA = DA - DE = 10 - 5 =5
Cross multiply,
x +3 = 6
Subtract 3 from both sides
x = 6 - 3
x = 3
x +1 = 3+ 1 = 4
The possible answer for the above equation is x=-12 or x=2
Answer: Option 1
Explanation:
Given:
To Find:
The possible value of x in the above equation
Solution:
Given equation;
By using the options given the question we get
Option 1; If x=-12 0r x=2
Substitute these value in the equation we get
[144-120+12]=36
[24+12]=36
36=36
Thus both the L.H.S=R.H.S
Hence Option 1 gives the correct value of x
Result:
Thus the possible value for x in the above equation is x=-12 or x=2
