Khan Academy's Algebra 1 course is built to deliver a comprehensive, illuminating, engaging, and Common Core aligned experience!The 25/4 and 7 is the result of completing the square method. To factor the equation, you need to first follow this equation: x^ 2 + 2ax + a^2. In x^2 +5x = 3/4, The a^2 is missing. To figure out the a, you need to take the 5 and divide it by 2 (because 2ax), which becomes 5/2. a=5/2. Then you need to square it, (because a^2) which becomes 5^2/2^2. Exercise 6. Exercise 7.

Incomplete sketch of y=-2 (x+5)^2+4. To finish our graph, we need to find another point on the curve. Let's plug x=-4 x = −4 into the equation. \begin {aligned} y&=-2 (-4+5)^2+4\\\\ &=-2 (1)^2+4\\\\ &=-2+4\\\\ &=2 \end {aligned} y = −2(−4+5)2 +4 = −2(1)2 +4 = −2 +4 = 2.An equation containing a second-degree polynomial is called a quadratic equation. For example, equations such as 2x2 + 3x − 1 = 0 2 x 2 + 3 x − 1 = 0 and x2 − 4 = 0 x 2 − 4 = 0 are quadratic equations. They are used in countless ways in the fields of engineering, architecture, finance, biological science, and, of course, mathematics..
