7x^2-14x + 5 = -x^2
Solve the equation for all real solutions

X = 1/2 and X = 5/4

Step-by-step explanation:

7x^2 - 14x + 5 = -x^2

8x^2 - 14x + 5 = 0

(2x - 1) + (4x - 5) = 0

To find X1

2x - 1 = 0

2x = 1

x = 1/2

To find X2

4x - 5 = 0

4x = 5

x = 5/4

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
