If s(x) = 2x2 + 3x - 4, and t(x) = x + 4 then s(x) · t(x) = ?
We will use the concept of functions to solve this.
Answer: If s(x) = 2x2 + 3x - 4, and t(x) = x + 4 then s(x) · t(x) = 2x3 + 11x2 + 8x - 16.
Let us solve it step by step.
Explanation:
Given:
s(x) = 2x2 + 3x - 4
t(x) = x + 4
Both s(x) and t(x) are functions of x and dependent on x.
s(x) · t(x) = (2x2 + 3x - 4)(x + 4)
= 2x3 + 3x2 - 4x + 8x2 + 12x - 16
= 2x3 + 11x2 + 8x - 16
Thus, if s(x) = 2x2 + 3x - 4 and t(x) = x + 4 then, s(x) · t(x) = 2x3 + 11x2 + 8x - 16.
