Question

Q.23, Solve the algebraic expression P(6P - 7)+5 and find its value at P = 1.​

Answer 1

Answer:

ans-4

Step-by-step explanation:

acc. to BODMAS we have to first solve the bracket, hence, subst. P=1

=1 (6×1-7)+5

=1 (6-7)+5

=1 (-1)+5

=1×-1+5

=-1+5

=4

Answer 2

• P(6P - 7) + 5 = 6P² - 7P + 5

• The value of the expression at P = 1 is 4

Given :

The expression P(6P - 7) + 5

To find :

• Simplify the given expression

• The value of the expression at P = 1

Solution :

Step 1 of 3 :

Write down the given expression

Here the given expression is P(6P - 7) + 5

Step 2 of 3 :

Simplify the given expression

P(6P - 7) + 5

= (P × 6P) - (P × 7) + 5

= 6P² - 7P + 5

Step 3 of 3 :

Find the value of the expression at P = 1

The given expression becomes 6P² - 7P + 5

The value of the expression at P = 1

= 6 × 1² - (7 × 1) + 5

= 6 - 7 + 5

= 6 - 2

= 4
