In ( (x+2)(x+7) ), what are the constant term and coefficient of (x) respectively?

Answer and explanation

Correct answer: (14) and (9)

To find both requested values, first expand the product or use the pattern for two binomials. The constant term comes from multiplying the two constants, 2 and 7, giving 14. The coefficient of x comes from the two middle products: x multiplied by 7 and 2 multiplied by x. These give 7x and 2x, whose sum is 9x. Therefore, the constant term and coefficient of x are 14 and 9 respectively, so option A is correct.

In full form, \\( (x+2)(x+7)=x^2+7x+2x+14=x^2+9x+14 \\). The number at the end is the constant term, while the number attached to x is its coefficient. Option B reverses these two values, and options C and D use individual numbers rather than the required product and sum. Keeping the sum for the middle coefficient and the product for the constant avoids this common error.
