Accepted Answer

When we expand the given expression using the FOIL method, we get:
x^2 + 11ea83f6_62a0_f2e0_b5a5_15954ca7ed36_TB6578_11_TB6578_11 x - 11ea83f6_62a0_f2df_b5a5_4f9fa8795d1a_TB6578_11_TB6578_11 x - 11ea83f6_62a0_f2df_b5a5_4f9fa8795d1a_TB6578_11_TB6578_11 * 11ea83f6_62a0_f2e0_b5a5_15954ca7ed36_TB6578_11_TB6578_11
Simplifying the expression gives:
x^2 - 11ea83f6_62a1_19f3_b5a5_654abe2ab2f5_TB6578_11_TB6578_11 x - 11ea83f6_62a1_19f4_b5a5_29c6d3afe8fa_TB6578_11_TB6578_11
Therefore, the correct choice is (C).

Question 15

(x + 1)(  + 3x - 5)- 
=

Accepted Answer

To expand the expression, we can use the distributive property and multiply each term in the first parentheses with every term in the second parentheses. This gives us:

(x + 1)(11ea83f6_62a0_095b_b5a5_3db3644de3d6_TB6578_11_TB6578_11 + 3x - 5) - 11ea83f6_62a0_095c_b5a5_15b42fe5d256_TB6578_11_TB6578_11
= (x)(11ea83f6_62a0_095b_b5a5_3db3644de3d6_TB6578_11_TB6578_11) + (1)(11ea83f6_62a0_095b_b5a5_3db3644de3d6_TB6578_11_TB6578_11) + (x)(3x) + (1)(3x) + (x)(-5) + (1)(-5) - 11ea83f6_62a0_095c_b5a5_15b42fe5d256_TB6578_11_TB6578_11
= 11ea83f6_62a0_095f_b5a5_59d1f13542c1_TB6578_11_TB6578_11 + 3x^2 - 2x - 5 - 11ea83f6_62a0_095c_b5a5_15b42fe5d256_TB6578_11_TB6578_11

Now we need to simplify the expression further. We can combine like terms to get:

11ea83f6_62a0_095f_b5a5_59d1f13542c1_TB6578_11_TB6578_11 - 11ea83f6_62a0_095c_b5a5_15b42fe5d256_TB6578_11_TB6578_11 + 3x^2 - 2x - 5

This matches the expression in choice B, so the answer is B.
