If one root of the equation is 4x^2- 2x+p-4 be the reciprocal of other. then find the value of p

SashulF [63]

Answer:

p = 8

Step-by-step explanation:

Let one root of the eqn. be alpha . Other root is 1/alpha .

We know that product of both roots of an quadratic eqn. is c/a where "c" is the co-efficient of the constant & "a" is the co-efficient of x^2.

Here "c" is p-4 & "a" is 4. And the product of roots is 1 ( ∵ prdouct of a number and its reciprocal is 1 )

$\frac{c}{a} = 1\\=> \frac{p - 4}{4} = 1\\=> p - 4 = 4\\=> p = 4 + 4 = 8$

german

Answer:

he age of girl 3 $\frac{1}{2}$ years ago is 8.5 years .

Step-by-step explanation:

Given as :

The present age of seventh grader girl = 12 years

Let The age of her 3 $\frac{1}{2}$ years ago = x years

So The age of girl $\frac{7}{2}$ years ago = x years

Now, According to question

The age of girl 3.5 years ago = 12 - 3.5

Or, The age of girl 3.5 years ago = 8.5 years

Hence The age of girl 3 $\frac{1}{2}$ years ago is 8.5 years . Answer
