Intro to Polynomials I will be able to multiply and simplify polynomials LT: • Rewrite into standard form • What are the missing terms? • What is the leading coefficient? • What is the constant term? • List the degrees • What is the degree of the polynomial? Today’s Agenda Success Criteria • I can multiply a polynomials • I can simplify • Do Now • Lesson • HW#23
Multiplying Polynomials By Monomials When multiplying, add the exponents! 1) Simplify: 5(7n – 2) Use the distributive property. 5 • 7n 35n – 10 – 5• 2
2) Simplify: 6a2 + 9a 3) Simplify:6rs(r2s - 3) 6rs • r2s 6r3s2 – 18rs – 6rs • 3
4) Simplify: 4t2(3t2 + 2t – 5) + 8t3 – 20t2 12t4 5) Simplify: - 4m3(-3m – 6n + 4p) 12m4 + 24m3n – 16m3p
4(d2 + 5d) + d(d2 – 7d + 2) 7) 4y(y2 – 8y + 6) – 3(2y3 – 5y2 + 2)
Multiplying Polynomials We use the distributive property to multiply two or more polynomials. • Distribute the first term of the first ( ) to ALL terms in the second ( ). • Distribute the second term of the first ( ) and continue until you are done with the first ( ). • Combine like terms.
