Answer (3)
3 p 2 − 2 p − 5 = a = 3 b = − 2 c = − 5 Δ = ( − 2 ) 2 − 4 ∗ 3 ∗ ( − 5 ) = 4 + 60 → 64 x 1 ; x 2 = 2 ∗ 3 − ( − 2 ) + / − 64 x 1 ; x 2 = 6 2 + / − 8 x 1 = 6 2 + 8 = 6 10 → 3 5 x 2 = 6 2 − 8 = 6 − 6 → − 1 3 p 2 − 2 p − 5 = ( x − 3 5 ) ( x + 1 )
To solve the quadratic equation 3 p 2 − 2 p − 5 = 0 using the quadratic formula, we find two solutions: p = 3 5 and p = − 1 . We calculated the discriminant, used it in the formula, and derived the values step by step. The quadratic equation can also be factored as 3 ( p − 3 5 ) ( p + 1 ) .
