Web2x^2+8x-5=0 Complete the square on the x-terms and keep the equation balanced 2 (x^2+4x+4) = 5+2*4 Factor the left side and simplify the right 2 (x+2)^2 = 13 (x+2)^2 = 13/2 Take the square root of both sides and rationalize the denominator on the right. (x+2) = sqrt26/2 or x+2 = -sqrt26/2 x = -2+ sqrt26/2 or x = -2-sqrt26/2 =============== Cheers, Web6 Oct 2024 · (8x+5)-(4x+2)8x+5-4x-2 4x+3Hope this helps.
