Question

find the value of the polynomial 7x-3x+5at x=-2

Answer 1

Answer :

• The value of the polynomial is -3

Given :

• 7x - 3x + 5
• x = -2

To find :

• Value of the polynomial

Solution :

⇛ 7x - 3x + 5

⇛ x = -2

⇛ 7(-2) - 3(-2) + 5

⇛ (-14) -(-6) + 5

⇛ -8 + 5

⇛ -3

Hence , The value of the polynomial is -3
