Answer:

The quadratic equation is: [tex]x^2-11x+28=0\\[/tex]

Step-by-step explanation:

The quadratic equation with given solutions [tex]a[/tex] and [tex]b[/tex] can be written as:

[tex](x-a)(x-b)=0[/tex]

Given:

Solutions are 4 and 7.

The quadratic equation can be written as:

[tex](x-4)(x-7)=0\\[/tex]

We simplify it further to get it in standard form.

Using FOIL(Firsts Outsides Insides Lasts )

[tex](x\times x)+(x\times(-7))+((-4)\times x)+(-4\times(-7))=0\\\\x^2-7x-4x+28=0\\[/tex]

Combining like terms:

[tex]x^2-11x+28=0\\[/tex]

The quadratic equation is: [tex]x^2-11x+28=0\\[/tex]
