Which is a solution to the equation?<br> (x - 3)(x - 5) = 35<br> x= -8<br> x=-5<br> x=2<br> x = 10
JulijaS [17]

(x-3)(x-5)=35

Multiply the brackets together

x*x-5*x-3*x-3*5

x^2-8x+15=35

Move +35 to the other side. Sign changes from +35 to -35

x^2-8x+15-35=35-35

x^2-8x-20=0

(x-10)(x+2)=0

x-10=0     x+2=0

Move -10 to the other side. Sign changes from -10 to +10

x-10+10=0+10   x+2-2=0-2

 x=10                      x=-2

Answer: x=10
