17 Μαΐ 2024 · Here, 3 linear equations are given with 3 variables x, y, and z. The equations are: 3x+2+y+z=8, 11x-9y+23z=27, 8x-5y=10. We will use the MINVERSE and MMULT functions to solve the given equations. Steps: Separate the coefficients in the different cells and format them as a matrix.
Rewrite 8y^{3}-27 as \left(2y\right)^{3}-3^{3}. The difference of cubes can be factored using the rule: a^{3}-b^{3}=\left(a-b\right)\left(a^{2}+ab+b^{2}\right). Polynomial 4y^{2}+6y+9 is not factored since it does not have any rational roots.
Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor.
When it comes to solving linear equations, Excel can be a powerful tool to streamline the process and quickly find solutions. Here, we will demonstrate how to set up a linear equation in Excel and provide a step-by-step guide on using the goal seek feature to solve for a variable.
Rewrite 8y3 as (2y)3. (2y)3 - 27 = 0. Rewrite 27 as 33. (2y)3 - 33 = 0. Since both terms are perfect cubes, factor using the difference of cubes formula, a3 - b3 = (a - b)(a2 + ab + b2) where a = 2y and b = 3. (2y - 3)((2y)2 + 2y ⋅ 3 + 32) = 0. Simplify. Tap for more steps... (2y - 3)(4y2 + 6y + 9) = 0.
