Answer:
The simplified solution is [tex]28x^{3}-22x^{2}-2x-42[/tex]
Step-by-step explanation:
we need to multiply the given expression;
[tex](7x^{2}+5x+7)(4x-6)[/tex]
we will multiply term wise
[tex]7x^{2}(4x-6)+5x(4x-6)+7(4x-6)[/tex]
[tex](7x^{2}\times 4x)-(7x^{2}\times 6)+(5x\times 4x)-(5x\times 6)+(7\times 4x)-(7\times 6)[/tex]
[tex]28x^{2+1}-42x^{2}+20x^{2}-30x+28x-42[/tex]
[tex]28x^{3}-22x^{2}-2x-42[/tex]
The simplified solution is [tex]28x^{3}-22x^{2}-2x-42[/tex]
