Sagot :

According to the given question we have the following equations:

a. x2+3x-3=0

b. 3x2-7x=12

a. X2+3x-3=0

The first step to calculate this equation is:

Move the -3 to the other side:

So, the equation would be:

X2+3x=3

x2+3x=5x

Therefore:

5x=3

x=3/5

a. The value of x would be 3/5

b. 3x2-7x=12

First step:

Multyply 3x to 2, so:

3x*2=6x

Next we can proceed to calculate the value of x:

6x-7x=12

-x=12

x=-12

b. The value of x would be -12
