Web 2x2 + 5x +2. Step 1 :trying to factor by splitting the middle term. 2x2 +5x− 120 = 0. Web x2+2x+5=0 two solutions were found : N 1 + n 2 = b = 5. In this technique, if we have to factorise an expression like ax2 + bx +c, we need to think of 2 numbers such that: = ( − 22) −(4 ⋅ 5 ⋅ ( − 2)) = 4 + 40. (2x2 + 5x) + 2 = 0 step 2 :trying to factor by splitting. We can split the middle term of this expression to factorise it. The quadratic formula gives two solutions, one when ± is addition and one when it is subtraction.
The equation is of the form ax2 + bx + c = 0 where: 2x2 +5x− 120 = 0. To use the direct factoring method, the equation must be in the form x^2+bx+c=0.this is achieved by dividing both sides of the equation by 2 More items copied to clipboard examples quadratic equation x2 − 4x − 5 = 0 trigonometry 4sinθ cosθ = 2sinθ linear equation y = 3x + 4 arithmetic 699 ∗533 matrix Web 2x2+5x+2=0 two solutions were found : Step 1 :equation at the end of step 1 : −5x2 +26x+ 5 = 0.
