Question

Identify the optimized code for the expression 
 x = (a + b) * (c + d) - e * (a + b);

Answer

t1 = a * c 
 t2 = b * d 
 t3 = t1 + t2 
 x = t3 - e

Answer

t1 = a + b 
 t2 = c + d 
 t3 = a + b 
 t4 = t3 * t2 
 t5 = e * t1 
 x = t4 - t5

Answer

t1 = a + b 
 t2 = c + d 
 t3 = t1 * t2 
 t4 = e * (a + b) 
 x = t3 - t4

Answer

t1 = a + b 
 t2 = c + d 
 t3 = t1 * t2 
 t4 = e * t1 
 t5 = t3 - t4 
 x = t5
