Question

UpStudy AI · Accepted Answer

Calculate or simplify the expression $$ (2*x^2+4*x-1)*(3*x^2-5) $$.
Simplify the expression by following steps:
- step0: Solution:
  $$\left(2x^{2}+4x-1ight)\left(3x^{2}-5ight)$$
- step1: Apply the distributive property:
  $$2x^{2}	imes 3x^{2}-2x^{2}	imes 5+4x	imes 3x^{2}-4x	imes 5-3x^{2}-\left(-5ight)$$
- step2: Multiply the terms:
  $$6x^{4}-10x^{2}+12x^{3}-20x-3x^{2}-\left(-5ight)$$
- step3: Remove the parentheses:
  $$6x^{4}-10x^{2}+12x^{3}-20x-3x^{2}+5$$
- step4: Subtract the terms:
  $$6x^{4}-13x^{2}+12x^{3}-20x+5$$
La expresión $$ (2x^{2}+4x-1)(3x^{2}-5) $$ simplificada es $$ 6x^{4}-13x^{2}+12x^{3}-20x+5 $$.
La expresión simplificada es $$ 6x^{4}-13x^{2}+12x^{3}-20x+5 $$.
