# 3x + x ^ 2-10

Divide -3, the coefficient of the x term, by 2 to get -\frac{3}{2}. Then add the square of -\frac{3}{2} to both sides of the equation. This step makes the left hand side of the equation a perfect square.

Tap for more steps x^2-10-(3*x)=0 . Step by step solution : Step 1 : Trying to factor by splitting the middle term 1.1 Factoring x 2-3x-10 The first term is, x 2 its coefficient is 1 . The middle term is, -3x its coefficient is -3 . The last term, "the constant", is -10 Step-1 : Multiply the coefficient of the first term by the constant 1 • -10 = -10 x2 − 3x − 10 = 0 To solve the equation, factor x2 −3x− 10 using formula x2 + (a +b)x+ ab = (x+a)(x+ b).

2-1<4+1. 8 Oct 2018 sufficient! 2) here we have no choice but to go back and solve the original equation: x2−3x=10 ==> x^2-3x Multiply 3x2 · 4x5 · 2x. Solution.

### May 30, 2011 · For the first system, if you substitute x^2 for the y in the second equation, you get a quadratic equation, which is 0=x^2+3x-10. Factoring this, you get: 0=(x+5)(x-2). Using the zero product property, x can equal either -5 or 2. Substituting -5 into the first equation, you get 25, and substituting 2 into the first equation, you get 4.

Click HERE to return {eq}\displaystyle (a) y = \frac{3x}{x^2 - 10}\\(b) x = \frac{3y}{y^2 - 10} {/eq} Functions: A given relation can only be a function if it is a one-to-one or a many-to-one relation. Graphically, a 3. x2 +y2 =10 Now we want to solve for each variable. At this point, you should take a moment and try to cleverly think of a way to solve for one of the three. Let’s plug in equations (1) and (2) into (3). This allows us to solve for .

Write 5x as 5*x. 3.

4. Write x 2-5x as x^2-5*x. 3. Use paranthesis() while performing arithmetic operations. Eg:1. Write sinx+cosx+tanx as sin(x)+cos(x)+tan(x) 2. Write secx*tanx as sec(x)*tan(x) 3.

3. Write x+5 as x+5. 4. Write x 2-5x as x^2-5*x. 3.

y = -2 + 3x. Graph either equation by finding two data points. By setting first x and then y equal to zero it is possible to find the y intercept on the vertical axis and 17 Jul 2018 Click here to get an answer to your question ✍️ What is the solution to this equation 3x -x + 8 + 5x -2 = 10.
