Algebra Problems Linear Equations
Can someone help me! I have these quadratic equations and linear algebra II problems? Please help!?
That sort of second-degree linear, or none. f (x) = (2x +3) (2x-3) Simplify both f (x) = (3x-1) ^ 2 f (x) = (x +5) (3x-4) and help the name of linear and quadratic terms of both constant f (x) = (x +3) ^ 2 f (x) = ax ^ 2 + bx + c
A second degree may be written in the form ax ^ 2 + bx + c, f (x) = (2x +3) (2x – 3) is a quadratic equation. The variables are nonlinear functions with power 2 or higher. quadratic functions did not vary with power ratings of 3 or more. f (x) = (3x – 1) ^ 2 f (x) = (3x – 1) (3x – 1) (foil) F = First = 3x * 3x = 9 x ^ 2 = 3x = extra-O * – 1 = Inside I -1 * 3x = 3x 3x =-L = -1 * -1 = 1 last 9 x ^ 2 – 3x – 3x + 1 (combine like terms) 9x ^ 2 – 6x + 1 <=== A f (x) = (X +5) (3x – 4) (foil) f (x) = 3x ^ 2 + 15x – 4x – 20 (combine like terms) f (x) = 3x ^ 2 + 11x – 20 <=== A f (x) = (x +3) ^ 2 (extension) f (x) = (x +3) (x +3) (leaf) f (x) = x ^ 2 + 3x + 3x + 9 (combination as terms) f (x) = x ^ 2 + 6x + 9 squares term term: x ^ 2, linear 6x; constant term: 9 (x) = ax ^ 2 + Bx + C quadratic term: Ax ^ 2, linear term: Bx constant term: C
