Ex 14.4, 14 Find and correct the errors in the following mathematical statements. (a + 4) (a + 2) = π‘Ž^2 + 8 Solving L.H.S : (a + 4) (a + 2) = a (a + 2) + 4 (a + 2) = (a Γ— a) + (a Γ— 2) + (4 Γ— a) + (4 Γ— 2) = π‘Ž^2 + 2a + 4a + 8 = π‘Ž^2 + 6a + 8 ∴ (a + 4) (a + 2) = 𝒂^𝟐 + 6a + 8 is the correct statement.
