Step-by-step explanation:
we will use here formula.
b+√b^2-4ac/2a
-
1)2b^2+17b+35
17√(17)^2-4×2×35/2×2
=17√289-280/4
=17√9/4
=17×3/4
=51/4
=12.75.
2)6x^2-39x-21
=39√(39)^2-4×6×21/2×6
=39√1521-504/12
=39√1017 /12
=39×31.8/12
=1240.2/12
=103.35
3)4x^2-17x+4
=17√(17)^2-4×4×4/2×4
=17√289-64/8
=17√225/8
=17×15/8
=225/8
=31.87
hope know you can contineu it...
