Answer 2

S O L U T I O N :

$\underline{\bf{Given\::}}$

The value of p = -2 .

$\underline{\bf{Explanation\::}}$

Putting the value of p in the given polynomials, we get;

1. 4p + 7

→ 4(-2) + 7

→ -8 + 7

→ -1

2. -3p² + 4p + 7

→ -3(-2)² + 4(-2) + 7

→ -3 × 4 + (-8) + 7

→ -12 - 8 + 7

→ -12 - 1

→ -13

3. -2p³ - 3p² + 4p + 7

→ -2(-2)³ - 3(-2)² + 4(-2) + 7

→ -2 × (-8) - 3 × 4 + (-8) + 7

→ 16 - 12 - 8 + 7

→ 4 - 1

→ 3

Thus,

The value of all polynomial will be -1, -13 & 3 .
