# 3x + x ^ 2 = 180

Simplifying 3x 2 + 25 = 180 Reorder the terms: 25 + 3x 2 = 180 Solving 25 + 3x 2 = 180 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-25' to each side of the equation. 25 + -25 + 3x 2 = 180 + -25 Combine like terms: 25 + -25 = 0 0 + 3x 2 = 180 + -25 3x 2 = 180 + -25 Combine like terms: 180 + -25 = 155 3x 2 = 155 Divide each side by '3'. x

Jan 20, 2012 · x + 5x + 2/3(x) = 180. Multiply both sides of equation by three: 3x + 15x + 2x = 540. 20x = 540. x = 27 x • 2 + x 3x ————————— = —— 2 2 Equation at the end of step 2 : 3x (—— + 90) - 180 = 0 2 Step 3 : Rewriting the whole as an Equivalent Fraction : 3.1 Adding a whole to a fraction Rewrite the whole as a fraction using 2 as the denominator : Free linear equation calculator - solve linear equations step-by-step integrate x/(x-1) integrate x sin(x^2) integrate x sqrt(1-sqrt(x)) integrate x/(x+1)^3 from 0 to infinity; integrate 1/(cos(x)+2) from 0 to 2pi; integrate x^2 sin y dx dy, x=0 to 1, y=0 to pi; View more examples » Access instant learning tools.

3x-6=x+7 . Use the distributive property to multiply 3 by x-2. 3x-6-x=7 . Subtract x from both sides. 2x-6=7 . Combine 3x and -x to get 2x. 3.1 Find the Vertex of y = x 2 +3x-180 Parabolas have a highest or a lowest point called the Vertex . Our parabola opens up and accordingly has a lowest point (AKA absolute minimum) . We know this even before plotting "y" because the coefficient of the first term, 1 , is positive (greater than zero). Each parabola has a vertical line of symmetry that passes through its vertex. Because of this 3*x^2-(180)=0 . Step by step solution : Step 1 : Equation at the end of step 1 : 3x 2 - 180 = 0 Step 2 : Step 3 : Pulling out like terms : 3.1 Pull out like factors : 3x 2 - 180 = 3 • (x 2 - 60) Trying to factor as a Difference of Squares : 3.2 Factoring: x 2 - 60 2008-09-22 Move all terms containing x to the left, all other terms to the right.
