Answer:
x =(8-√204)/2=4-√ 51 = -3.141
x =(8+√204)/2=4+√ 51 = 11.141
Explanation:
Factoring x2-8x-35
The first term is, x2 its coefficient is 1 .
The middle term is, -8x its coefficient is -8 .
The last term, "the constant", is -35
Step-1 : Multiply the coefficient of the first term by the constant 1 • -35 = -35
Step-2 : Find two factors of -35 whose sum equals the coefficient of the middle term, which is -8 .
-35 + 1 = -34
-7 + 5 = -2
-5 + 7 = 2
-1 + 35 = 34
