Urgent !

simplify (x − 4)(4x2 + x − 6).
4x3 − 16x2 − 10x + 24
4x3 + 15x2 + 10x − 24
4x3 − 15x2 − 10x + 24
4x3 + 16x2 + 10x − 24

4x³ − 15x² − 10x + 24

Distribute

x · 4x² + x · x + x · -6 + (-4) · 4x² + (-4) · x + (-4)(-6)

Simplify:

4x²x + xx - 6x - 4 · 4x² - 4x + 4 · 6

Further simplify (by adding and subtracting like terms)

4x³ − 15x² − 10x + 24

Hope this helps :)

Its the third choice:  4x^3 - 15x^2 - 10x + 24.

Step-by-step explanation:

(x − 4)(4x2 + x − 6)

= x(4x2 + x − 6) - 4(4x2 + x − 6)

= 4x^3 + x^2 - 6x - 16x^2 - 4x + 24

= 4x^3 - 15x^2 - 10x + 24.

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)
