Question

CH2 POLYNOMIALS - HOMEWORK SUMS
1. Use suitable identities to find the following products:
(x+3)(x-10)​

Answer 1

$(x + 3)(x - 10)$

we know an Algebraic identity-

$(x + a)(x + b) = {x}^{2} + (a + b)x + ab$

Here,a = 3

b = -10

${x}^{2} + (3 - 10)x + (3)( - 10)$

${x}^{2} - 7x - 30$

Answer 2

Answer:

The answer of your question is x2-7x+49

Step-by-step explanation:

(x)2+(3-10)X +(-7)2
