Solve for x: x^2-14x+52=7<br> PLEASE HAVE EXPLANATION AND I WILL MARK BRAINLIEST
ale4655 [162]

Answer:

x_1=9\\x_2=5

Step-by-step explanation:

To solve this problem, you must:

- Subtract 7 from  both sides of the equation:

x^{2}-14x+52-7=7-7\\x^{2}-14x+45=0

- Now, you can factor it. Choose two numbers whose sum -14 and whose product is 45. These numbers would be -9 and -5. Therefore, you obtain the following solution:

(x-9)(x-5)=0\\\\x_1=9\\x_2=5
