求解步骤

4^{2} + 34 - 84

数字相加/相减:

34 - 84 = - 50

= 4^{2} - 50

4^{2} = 16

= 16 - 50

数字相减:

16 - 50 = - 34

= - 34

e x p an d \frac{( s + 1 ) ( 5 s + 10 )}{s}

e x p an d \frac{2 x + 34}{x ( x + 16 )}

e x p an d (x^{2} - 2 x + 1) (1 + 0.1 x)

e x p an d \frac{50 s ^{3} + s ^{2} + s + 100}{s ^{2} ( s ^{2} + s + 100 )}

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