Question

Determine whether the given values are solutions of the given equation or not:
2x2
- x + 9 = x2
+ 4x + 3, x = 2, x = 3

Answer 1

Answer:

yes both are the solutions...

Step-by-step explanation:

Equation :-

p(x) = 2x^2 - x + 9 = x^2 + 4x + 3

Given values -

i) x = 2

Checking ,

p(2) = 2 (2)^2 - 2 + 9 = 2^2 + 4(2) + 3

8 + 9 -2 = 4 + 8 + 3

15 = 15

☆ Hence, this is a solution of the given equation.

ii) x = 3

p(3) = 2(3)^2 - 3 + 9 = 3^2 + 4(3) + 3

18 + 9 - 3 = 9 + 12 + 3

24 = 24

☆ Hence, this is a solution of the given equation.
