To calculate: The simplified value of the expression (3x+4)2 .

Expert Solution

Answer to Problem 29E

The value of the expression (3x+4)2 is 9x2+24x+16 .

Explanation of Solution

Given information:

The expression (3x+4)2 .

Formula used:

The special product formula of perfect square to multiply the algebraic expressions is mathematically expressed as,

  (A+B)2=A2+2AB+B2

Calculation:

Consider the given expression (3x+4)2 .

Recall the special product formula of perfect square to multiply the algebraic expressions is mathematically expressed as,

  (A+B)2=A2+2AB+B2

Apply it,

  (3x+4)2=(3x)2+2(3x)(4)+(4)2=9x2+24x+16

Thus, the value of the expression (3x+4)2 is 9x2+24x+16 .
