Question

the following are the values of a, b, and c that andy and andrew got when they expressed 10 - 7x - 4x² in standard form andy: a = 4; b =7; c = -10 andrew: a = -4; 6-7; c= 10 who do think got the correct values of a, b, and c​

Answer 1

Step-by-step explanation:

Given quadratic expression:

10 - 7x - 4x^2.

Expressing it in standard form is given below:

standard form: ax^2 + bx + c

conversion: -4x^2 -7x + 10

You can clearly see that:

a = -4

b = -7

c = 10

In your question i think there is a typo error for the values of a,b,c andrew got. I guess you have written 6-7 instead of b= -7. Check that once.

If there is error than andrew got correct values.

If no error then none of them got correct values.

Pretty simple question if you can identify the coefficient of quadratic equation then its a matter of seconds to solve.
