Write the expression (4x-6) x 6(2x+7)

48x² + 96x - 252  

Step-by-step explanation:

    (4x - 6) × 6(2x + 7)    Reorder the factors

= 6(4x – 6)(2x+ 7)          Multiply the binomials

= 6(8x² + 16x - 42)         Remove parentheses

= 48x² + 96x - 252

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
