How do you solve a x2 + bx + c = 0?
All equations of the form a x 2 + b x + c = 0 can be solved using the quadratic formula: 2 a − b ± b 2 − 4 a c . The quadratic formula gives two solutions, one when ± is addition and one when it is subtraction. This equation is in standard form: ax^ {2}+bx+c=0.
Can x2 + 4x +2 = 0 be factored?
It can be x = −0.586 or x = −3.414 Explanation: x2 + 4x +2 = 0 cannot be factored because there are no factors of 2 which add up to 4. It can be x2+5x+2=0 Two solutions were found : x = (-5-√17)/2=-4.562 x = (-5+√17)/2=-0.438 Step by step solution : Step 1 :Trying to factor by splitting the middle term 1.1 Factoring x2+5x+2
How do you solve an equation with a square root?

How do you find the complete solution to the equation?
Set the first factor equal to 0 0. Add 2 2 to both sides of the equation. Take the square root of both sides of the equation to eliminate the exponent on the left side. The complete solution is the result of both the positive and negative portions of the solution. Tap for more steps…
All equations of the form a x 2 + b x + c = 0 can be solved using the quadratic formula: 2 a − b ± b 2 − 4 a c . The quadratic formula gives two solutions, one when ± is addition and one when it is subtraction.
How to find the extraneous root of x^2+x+1=0?
In effect, you have taken the equation x^2+x+1=0, divided by x to get x+1+\\frac1x=0 and then multiplied by x-1 to get x^2-\\frac1x=0. The extraneous root 1 is the solution of x-1=0,
How many solutions does the quadratic formula give?
The quadratic formula gives two solutions, one when ± is addition and one when it is subtraction. All equations of the form a x 2 + b x + c = 0 can be solved using the quadratic formula: 2 a − b ± b 2 − 4 a c .
All equations of the form a x 2 + b x + c = 0 can be solved using the quadratic formula: 2 a − b ± b 2 − 4 a c . The quadratic formula gives two solutions, one when ± is addition and one when it is subtraction. Subtract 12 from both sides of the equation. Subtract 1 2 from both sides of the equation. Subtracting 12 from itself leaves 0.
