Answer to Problem 19CLR

The value of the expression (9z3)(5z+4) is 45z2+21z12 .

Explanation of Solution

Given information:

The expression is (9z3)(5z+4) .

Formula used:

When an algebraic expression multiply by group of algebraic terms connected with addition or subtraction is equal to multiplication of expression with the terms separately. That is a(b±c)=(a×b)±(a×c)

If two terms have the same sign, their product is positive.

If two terms have the opposite sign, their product is negative.

We can add terms of an algebraic expression which is like.

Calculation:

Consider the expression is (9z3)(5z+4) .

Recall that when an algebraic expression multiply by group of algebraic terms connected with addition or subtraction is equal to multiplication of expression with the terms separately. That is a(b±c)=(a×b)±(a×c)

Use it,

  (9z3)(5z+4)=((9z3)×5z)+((9z3)×4)=(9z×5z)+(3×5z)+(9z×4)+(3×4)

Again recall that If two terms have the same sign, their product is positive and

if two terms have the opposite sign, their product is negative.

Apply it,

  (9z×5z)+(3×5z)+(9z×4)+(3×4)=45z215z+36z12

Also we know that we can add terms of an algebraic expression which is like.

Again apply it,

  45z215z+36z12=45z2+21z12

Thus, the value of the expression (9z3)(5z+4) is 45z2+21z12 .
