Solve each quadratic equation. show your work.
x^2 + 3x = 10

Step-by-step explanation:

We shall use middle term split method to find the factor

here middle term is 3 ,factor of -10 which gives -3  on adding

such numbers are -10 = 5 and -2

                             5+(-2) = 3

                  And then making two groups and simplifying it ,we get the roots

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

5x+10 is the correct one

hope this
