2x(x + 3) − 1(x +3) = 0. The quadratic equation in standard form is ax2 + bx +c, where a = 2, b = − 5, and c = − 3. 2x2 + 2x+3x+3 2 x 2 + 2 x + 3 x + 3. Now we can equate the factors with zero to obtain the solutions. Medium solution verified by toppr we have, 2x 2−5x+3=0 ⇒x 2− 25x+ 23=0 (dividing throughough by 2) ⇒x 2− 25x=− 23 (shifting the constant term on rhs) ⇒x 2−2(45)x+(45)2=(45)2− 23 (adding (21coeff.ofx)2 onboth sides) ⇒(x− 45)2= 1625− 23⇒(x− 45)2= 161⇒x− 45=± 41⇒x= 45± 41 Una función cuadrática univariada (variable única) tiene la forma f (x)=ax²+bx+c, a≠0 en este caso la variable única es x. You write down problems, solutions and notes to go back. Quadratic formula x = −b ± √b2 −4ac 2a plug the given values into the formula and solve. 2x2 + 6x −1x −3 = 0. #class10like my facebook page learn basic.
