Description

This video demonstrates solving a quadratic equation in standard form where a and c are positive, and b is negative. The standard form is ax2 + bx + c = 0. The quadratic formula is used, with step-by-step substitution of a = 4, b = -5, and c = 1 into the formula. Key vocabulary includes quadratic equation, quadratic formula, roots, and real numbers. The solution simplifies terms, notes the plus-minus for two roots, and determines the two real roots.
