1.1 EQUATIONS Linear Equations is of the form ax + b = c , where a, b, and c are constants and a 0. Strategy for solving linear equations: [1] Clear parentheses, using the distributive property, and clear fractions or decimals by multiplying both side by LCD or a power of 10; [2] collect like terms on each side; [3] use addition (subtraction) property of equality to get on one side all terms containing the variable for which the equation is being solved and all remaining terms on the other side of the equal side; [4] use multiplication (division) property of equality to get the variable by itself on one side; [5] check your answer. 1. 8x + 5 = 29 2. 4a + 5 = 7a – 19 3. x 3 5 5 4 8 6 + = 4. 0.03x + 0.004 = 3.514 5. 3(2y + 3) = 7y – 5 6. 5x – (6x + 2) = -3(x + 5) 7.

1. 2 QUADRATIC EQUATIONS Quadratic Equations: These are second-degree equations, meaning the largest exponent is two. Standard form is ax 2 + bx + c = 0 , where a , b , and c are coefficients of x.
