13 to the third power = 169
---------------------------------------------
20-8= 12
---------------------------------------------
2+6=8
---------------------------------------------
169 x 12 = 2028
---------------------------------------------
2028/8 = 253.5
Step-by-step explanation:
Given expression is x⁴-kx²+4 =0
x−2 is a factor of the given expression.
So, x=2
Substitute in the equation, we get
2⁴-k(2)²+4
⇒16+4k+4=0
⇒4k=−20
⇒k=−5
