Given:

Since the quadratic equation is equal to 0, we need to solve for x. Let's factor. Since a ≠ 1, we can easily solve. We need to find out what factors of 10 add up to 7. I know that 5*2 = 10 and 5+2 = 7. This fits out problem perfectly. Now that we have that, we can simplify it into two binomials:

Now, if it was not equal to zero, we would be done. However, we are not done. We need to set both terms equal to 0 to solve for x.

To isolate x, subtract 2 from both sides to cancel the +2 on the left.

Let's do the other one:

Same thing, subtract 5 from both sides to isolate x.

So, in conclusion, your solutions are:

Step-by-step explanation:

Answer:
82
Step-by-step explanation:
given:x=10
Evaluating,
(10)²-2(10)+2
=100-20+2
=80+2
=82
Pls mark me brainliest
Answer:
Sum of 3 angles in a triangle=180
x+55+72= 180
x+ 127=180
x= 180-127
x= 53
