Example text

Before you perform any mathematical operation, that quantity of water is unknown. qxd:JSB 24 12/18/08 11:44 AM Page 24 algebra basics TIP: If we do not know the value of a quantity in a problem, that value is an unknown. We can write a sentence to show what happened to the volume of water in the beaker even though we don’t know how much water was added. A symbol can hold the place of the quantity of water that was added. Although we could use any symbol to represent this quantity, we usually use letters, and the most commonly used letter in algebra is x.

The exponent of v in the answer is 4. (15v9)(3v5) = 5v4. 2. Begin with the coefficients: –63 ÷ –7 = 9. Carry the base (a) from the dividend into the answer. There are no bases in the divisor that are not in the dividend, and vice versa. Next, subtract the exponent of a in the divisor from the exponent of a in the dividend: 1 – 8 = –7. The exponent of a in the answer is –7. (–63a)(–7a8) = 9a–7. 3. Begin with the coefficients: 30 ÷ –5 = –6. Carry the bases (p, q, and r) from the dividend into the answer.

Each term has a base of y, so your answer has a base of y. Next, add the exponents of y from each term: 9 + 9 = 18. (–3y9)(–y9) = 3y18. 4. Multiply the coefficients: (10)(–2) = –20. Each term has a base of g and a base of h, so your answer has both g and h in it. Next, add the exponents of g from each term: 3 + 5 = 8. The exponent of g in your answer is 8. Finally, add the exponents of h from each term: 5 + 9 = 14. The exponent of h in your answer is 14. (10g3h5)(–2g5h9) = –20g8h14. 5. Multiply the coefficients: (9)(9) = 81.
