Question

5m square plus 5m is equal to 1 find quadratic formula
5m square+5m=1
​

Answer 1

Answer:

The first term is, 2m2 its coefficient is 2 .

The middle term is, -5m its coefficient is -5 .

The last term, "the constant", is -3

Step-1 : Multiply the coefficient of the first term by the constant 2 • -3 = -6

Step-2 : Find two factors of -6 whose sum equals the coefficient of the middle term, which is -5 .

-6 + 1 = -5 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -6 and 1

2m2 - 6m + 1m - 3

Step-4 : Add up the first 2 terms, pulling out like factors :

2m • (m-3)

Add up the last 2 terms, pulling out common factors :

1 • (m-3)

Step-5 : Add up the four terms of step 4 :

(2m+1) • (m-3)

Which is the desired factorization

Answer 2

Step-by-step explanation:

5m²+5m=1

5m²+5m-1=0

d=b²-4ac

=(5)²-4×5×1

=25-20

=5

so, m= (-b+ sq.rt.d)/2a

= (-5+

$\sqrt{5}$

)/2×5

= +

$\sqrt{5}$
