Question

14xsquare(3xsquare-19x+30)by 4x(3x-10)

Answer 1

Answer:

$: \implies \sf \dfrac{7x^2 - 21x}{2}$

Step-by-step explanation:

$: \implies \sf \dfrac{14x^2 (3x^2 - 19x + 30)}{4x (3x-10)}$

$: \implies \sf \dfrac{14x(3x^2-9x-10x+30)}{4(3x-10)}$

$: \implies \sf \dfrac{7x(3x^2-9x-10x+30)}{2(3x-10)}$

$: \implies \sf \dfrac{7x[3x(x-3) - 10(x-3)]}{2(3x-10)}$

$: \implies \sf \dfrac{7x(x-3) \times (3x-10)}{2(3x-10)}$

$: \implies \sf \dfrac{7x(x-3)}{2}$

$\qquad \large \dag{\underline{\boxed{\bf \dfrac{7x^2 - 21x}{2}}}}$
