Question

h^2+2h- 120 with full formula

Answer 1

Answer:

h is equal to 12 or -10

Step-by-step explanation:

h²+2h-120

so here I'm gonna solve by splitting the middle term

product= -120, sum=2

numbers = -12, 10

h²+10h-12h-120 = 0

now we'll take the common  factors out

h(h+10) -12(h+10) = 0

(h-12) (h+10) = 0

h-12 = 0, h+10= 0

therefore, h= -10, h= 12

Answer 2

h^2+2h-120=0
By using formula
X= -b+- _/b^2-4ac / 2a
h= -2 +- _/2^2 - 4*1*-120 / 2*1
h= -2 +- _/4+480 /2
h= -2 +- 2_/121

Taking +
h = -2 + 2_/121 /2
h= -2(1-_/121) /2
h = -(1-_/121)

Taking -
h= -2 - 2_/121 /2
h= -2(1+_/121) /2
h= -(1+_/121)

I hope this answer will help uhhhh
