which is a solution to (x - 2)(x + 10) = 13?\n○ x = 3\n○ x = 8\n○ x = 10\n○ x = 11
Answer
Explanation:
Step1: Substitute (x = 3)
((3 - 2)(3 + 10)=1\times13 = 13)
Step2: Substitute (x = 8)
((8 - 2)(8 + 10)=6\times18=108\neq13)
Step3: Substitute (x = 10)
((10 - 2)(10 + 10)=8\times20 = 160\neq13)
Step4: Substitute (x = 11)
((11 - 2)(11 + 10)=9\times21=189\neq13)
Answer:
A. (x = 3)
