You can also see that the midpoint of r and s corresponds to the axis of symmetry of the parabola represented by the quadratic equation y=x^2+Bx+C.Step 1 : Equation at the end of step 1 : x • (x - 1) • (x - 2) = 0 Step 2 : Equation at the end of step 2 : x • (x - 1) • (x - 2) = 0 Step 3 : Theory - Roots of a product : 3.1 A product of several terms equals zero. When a product of two or more terms equals zero, then at least one of the terms must be zero.After you enter the expression, Algebra Calculator will plug x=6 in for the equation 2x+3=15: 2(6)+3 = 15.

For x+6=2x+3, check (correct) solution x=3: x+6=2x ...2x2+1=0 Two solutions were found : x= 0.0000 - 0.7071 i x= 0.0000 + 0.7071 i Step by step solution : Step 1 :Equation at the end of step 1 : 2x2 + 1 = 0 Step 2 :Polynomial Roots ...2.2 Solving x2+x+1 = 0 by Completing The Square . Subtract 1 from both side of the equation : x2+x = -1. Now the clever bit: Take the coefficient of x , which is 1 , divide by two, giving 1/2 , and finally square it giving 1/4. Add 1/4 to both sides of the equation : On the right hand side we have :1/x^2. Natural Language. Math Input. Extended Keyboard. Examples.
