Web29 mrt. 2024 · Transcript. Example 13 Find the roots of the following quadratic equations, if they exist, using the quadratic formula: (ii) x2 + 4x + 5 = 0 x2 + 4x + 5 = 0 Comparing … WebA quadratic equation has two roots which may be unequal real numbers or equal real numbers, or numbers which are not real. If a quadratic equation has two real equal roots α, we say the equation has only one real solution. Example: Let 3x 2 + x - 2 = 0 be a quadratic equation. Clearly, 3 ∙ (-1) 2 + (-1) - 2 = 0

WebIf by "regular equation" you mean, for example, 4x-8=32, it is definitely like solving a regular equation. It just uses squares and square roots, so if you simplified an equation down to x^2 = 9, you could just take the square root of both sides (this "un-squares" it :D) and you would get x = 3. Does that help? -- WriterScientist ( 2 votes) bau appWebIn the equation ax 2 +bx+c=0, a, b, and c are unknown values and a cannot be 0. x is an unknown variable.
