Example 5: Simplify the expressions and evaluate them as directed:0) x – InterviewSolution

1.	Example 5: Simplify the expressions and evaluate them as directed:0) x (x 3) + 2 for x 1,(ii) 3y (2y -7)-30-4)-63 for y--2
Answer» 1) x(x-3)+2 = 1(1-3)+2 = -2+2=02) 3y(2y-7)-3(y-4)-63 = 3(-2)(-4-7)-3(-2-4)-63=66+18=84
