3x + x 2 = 4

Solve Quadratic Equation by Completing The Square. 3.2 Solving x2-3x-4 = 0 by Completing The Square . Add 4 to both side of the equation : x2-3x = 4. Now the clever bit: Take the coefficient of x , which is 3 , divide by two, giving 3/2 , and finally square it giving 9/4. Add 9/4 to both sides of the equation :

Try it risk-free Then substitute −3x + 6 for y in the second equation. Use the solution for x and either equation to find y. The solution is (2, 0). 4. 2x + 3y = 4.

squaring both the sides. 9x^2 + 4/x^2 + 12 = 49 ( as ( a+ b )^2 = a^2 + b^2 + 2ab ) 9x^2 + 4/x^2 = 37 ----- (i) we know that ( a - b )^2 = a^2 + b^2 - 2ab ( a - b )^2 = a^2 + b^2 - 2ab + 2ab - 2ab ( adding and subtracting 2ab ) ( a - b )^2 = ( a + b )^2 - 4ab. Thus replacing a and b with 9x^2 and 4/x^2 respectively we get , 2. We can solve the integral $\int\sqrt{x^2+4}dx$ by applying integration method of trigonometric substitution using the substitution See full list on quickmath.com Oct 16, 2015 · Write the quadratic inequality in standard form: f (x) = x^2 - 3x - 4 > 0. First, solve y = 0 to find the 2 x-intercepts (real roots).

For what value of k, is the polynomial f(x) = 3x 4 – 9x 3 + x 2 + 15x + k completely divisible by 3x 2 – 5 ? Answer. k + 10 = 0 ⇒ k = –10. Related. Find all the zeroes of the polynomial 3x^4 + 6x^3 - 2x^2 - 10x - 5 Obtain all zeroes of 3x^4 – 15x^3 + 13x^2 + 25x – 30

Use the solution for x and either equation to find y. The solution is (2, 0). 4.

The middle term is, -3x its coefficient is -3 . The last term, "the constant", is -4 Step-1 : Multiply the coefficient of the first term by the constant 1 • -4 = -4 Step-2 : Find two factors of -4 whose sum equals the coefficient of the middle term, which is -3 . To solve the equation, factor x^{2}-3x-4 using formula x^{2}+\left(a+b\right)x+ab=\left(x+a\right)\left(x+b\right). To find a and b, set up a system to be solved. 1,-4 2,-2 .

3.2 Solving x2-3x-4 = 0 by Completing The Square . Add 4 to both side of the equation : x2-3x = 4. Now the clever bit: Take the coefficient of x , which is 3 , divide by two, giving 3/2 , and finally square it giving 9/4. Add 9/4 to both sides of the equation : Jun 11, 2013 · Given 3x + 2/x = 7. squaring both the sides. 9x^2 + 4/x^2 + 12 = 49 ( as ( a+ b )^2 = a^2 + b^2 + 2ab ) 9x^2 + 4/x^2 = 37 ----- (i) we know that ( a - b )^2 = a^2 + b^2 - 2ab ( a - b )^2 = a^2 + b^2 - 2ab + 2ab - 2ab ( adding and subtracting 2ab ) ( a - b )^2 = ( a + b )^2 - 4ab.
