Solve each equation using the zero-factor property. 36x² + 60x + 25 = 0

검증된 단계별 안내

Recognize that the equation $36x^2 + 60x + 25 = 0$ is a quadratic equation and check if it can be factored into the form $(ax + b)(cx + d) = 0$.

Look for two numbers that multiply to $36 \times 25 = 900$ and add up to $60$, which will help in factoring the middle term.

Rewrite the middle term \$60x$ as the sum of two terms using the numbers found in the previous step, then group the terms to factor by grouping.

Factor out the greatest common factor from each group to express the quadratic as a product of two binomials, i.e., $(mx + n)(px + q) = 0$.

Apply the zero-factor property by setting each factor equal to zero: $mx + n = 0$ and $px + q = 0$, then solve each linear equation for $x$.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Zero-Factor Property

The zero-factor property states that if the product of two factors equals zero, then at least one of the factors must be zero. This property is essential for solving polynomial equations by factoring, as it allows us to set each factor equal to zero and solve for the variable.

Factoring Quadratic Expressions

Factoring quadratic expressions involves rewriting a quadratic equation in the form ax^2 + bx + c as a product of two binomials. This step is crucial before applying the zero-factor property, as it breaks down the equation into simpler parts that can be individually set to zero.

Solving Quadratic Equations

Solving quadratic equations means finding the values of the variable that satisfy the equation. After factoring and applying the zero-factor property, each resulting linear equation is solved to find the roots or solutions of the original quadratic.
