Answer:

-5/8a - 2.8b

Step-by-step explanation:

-3/8a + 3.2b + (-6b) - 1/4a

=> -3/8a + 3.2b + (-6b) - 2/8a

=> -5/8a + 3.2b - 6b

What is the value of b2-4ac for the following equation? 5x2+7x=6

poizon [28]

Answer:

169

Step-by-step explanation:

Given data

The function is

5x^2+7x=6

rearrange

5x2+7x-6=0

From the above expression, we can see that

a=5

b=7

c=-6

Substitute into the expression b^2-4ac

=7^2-4*5*-6

= 49-(-120)

=49+120

=169

Hence the answer is 169
