Question

My dear friends pls ans with step by step explanation very urgent do not post irrelevant answers if u i will report ​

Answer 1

Answer:

(a) P²-2P-100 = -92

(b) -P²+4P+7 = -5

Step-by-step explanation:

Given: P = -2

(a) P²-2P-100 = (-2)² - 2(-2) - 100 = 4+4-100 = -92

(b) -P²+4P+7 = -(-2)² + 4(-2) + 7 = -4-8+7 = -5

Answer 2

Answer:

here u go

Step-by-step explanation:

a)

p²= -2²= 4

p² = 4 (eqn 1)

2p= -4 (eqn 2)

applying equation 1 and 2

4-(-4)-100 = -92

b)

-p²= -(-2²)

-p²= 4 (eqn 3)

4p = -8 (eqn 4)

applying equation 3 and 4

4+(-8)+7= 3

hence proved

hope it helps you
