WebHere, we can use them to group 4 and 2 —the numbers being added. 5 ⋅ (4 + 2) This is the correct way to write the expression. Based on the order of operations, always solve … WebNow we're going to see if the equation is true. If the left side is equal to the right side, our answer is correct. 4 (3 ⋅ 3 - 8) = 4. We'll follow the order of operations, with parentheses first. 3 ⋅ 3 is 9, and 9 - 8 is 1. 4 (1) = 4. Now that we've simplified the parentheses, all we have to do is multiply 4 times 1.
WebQuadratic Equation in Standard Form: ax 2 + bx + c = 0. Quadratic Equations can be factored. Quadratic Formula: x = −b ± √ (b2 − 4ac) 2a. When the Discriminant ( b2−4ac) is: positive, there are 2 real solutions. zero, there is one real solution. negative, there are 2 complex solutions. Web3x + 2 Writing Algebraic Expressions You can translate word phrases into variable expressions. Examples: Three more than a number = x + 3 The quotient of a number and 8 = y/8 Six times a number = 6 x n or 6n 15 less than a number = z – 15 The quotient of 30 and a number plus 10 = 30/x + 10.
