Answer» 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. Hope it will HELP you :) |
