Web23 okt. 2016 · To solve this question, we can sub in −2x wherever we see a y in our original equation (substitution method). x2 +x( − 2x) +( − 2x)2 = 1 x2 −2x2 +4x2 = 1 3x2 = 1 x2 = 1 3 x = ± √1 3 STEP 5: Now that we know the x-value of the point, we can easily find the y-value of the point because we know y = −2x where the tangent line is horizontal. WebThese are the different parts of the algebraic expression. Let us consider an expression, 2x+4y-9. Here, the parts of the expression are: Coefficients are 2 and 4. Constant is 9. Variables are x and y. Terms are 2x, 4y and y. Mathematical operators used are plus (+) and minus (-). Now, let us discuss the terms, factors and what is a coefficient ...
