Answer 2

The value at p = 1, 3 are

Given:

Equation = p(6p - 7) + 5

To find:

The value at p = 1 , 3.

Step-by-step explanation:

p(6p - 7) + 5

6p² - 7p + 5                      (a)

At p = 1.

On substituting the value of p in the equation (a)

  6p² - 7p + 5

= 6(1)² - 7(1) + 5

= 6 - 7 + 5

= 12 - 7

= 4

At p = 3.

Substituting the value of p in equation (a)

6p² - 7p + 5

= 6(3)² - 7(3) + 5

= 54 - 21 + 5

= 33 + 5

= 38
