解答

展开

(a_{0} x + a_{1} y)^{2} + p y

a_{0}^{2} x^{2} + 2 a_{0} a_{1} x y + a_{1}^{2} y^{2} + y p

求解步骤

(a_{0} x + a_{1} y)^{2} + p y

= (a_{0} x + a_{1} y)^{2} + y p

展开

(a_{0} x + a_{1} y)^{2} : a_{0}^{2} x^{2} + 2 a_{0} a_{1} x y + a_{1}^{2} y^{2}

= a_{0}^{2} x^{2} + 2 a_{0} a_{1} x y + a_{1}^{2} y^{2} + y p

e x p an d 2 x^{\frac{2}{3}} (x + 3)

s im pl i f y x (x + y)

s im pl i f y (ab + \frac{9}{2}) (- \frac{9}{2} + ab)

e x p an d tan^{2} (x) - sin^{2} (x) (cot^{2} (x) + tan (x))^{2}

e x p an d \frac{2 x ( x + 1 ) ( x - 1 )}{x ^{4} + 6 x ^{2} + 1}
