=4a-7b+c-2a+6b+c

=2a-b+2c

to subtract 2a-6b-c from 4a-7b+c

4a-7b+c -(2a-6b-c)

=4a-7b+c-2a+6b+c

=2a-b+2c

The standard quadratic equation using the given set of solutions {−4,7} is y=x2−3x−28 y = x 2 - 3 x - 28 .

The quadratic equation will be[tex]x^2 -11x +28 =0[/tex]

Step-by-step explanation:

To frame the quadratic equation using the solutions as 4 and 7, we can go in the reverse order of finding the solution.

• Let x =  4, and x = 7

• Then solutions can be written as [tex](x-4)[/tex] and [tex](x-7)[/tex]

• Now, taking the product of the two terms and equating to zero

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

• On multiplication, we obtain,

[tex]x^2-7x-4x+28 = 0[/tex]

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

• Hence, the desired quadratic equation is [tex]x^2 -11x +28 =0[/tex]
