We have the following equation:
2x2-3x + 1
Using resolver we have:
x = (- b +/- root (b2-4ac)) / (2a)
Substituting values we have:
x = (- (- 3) +/- root ((- 3) 2-4 (2) (1))) / (2 (2))
Rewriting:
x = (3 +/- root (9-8)) / (4)
x = (3 +/- root (1)) / (4)
b2-4ac = 1> 0
root(b2-4ac) = 1 < 3
Answer:
Two positive real solutions

The altitude of a triangle is 2 m longer than its base. What are the dimensions of the altitude and the base if thearea of the t

HACTEHA [7]

Step-by-step explanation:

Let base of triangle be x m.

Therefore, altitude =( x + 2)m

$area \: of \: \triangle = \frac{1}{2} \times base \times altitude \\ \\ 40 = \frac{1}{2} \times x \times (x + 2) \\ \\ 80 = {x }^{2} +2x \\ \\ {x}^{2} + 2x - 80 = 0 \\ {x}^{2} + 10x - 8x - 80 \\ x(x + 10) - 8(x + 10) = 0\\ (x + 10)(x - 8) = 0 \\ x + 10 = 0 \: \: or \: \: x - 8 = 0 \\ x = - 10 \: \: or \: \: x = 8 \\ base \: can \: not \: be \: - ve \\ x \neq - 10 \\ x = 8 \\ x + 2 = 8 + 2 = 10 \\$

Therefore

Altitude = 10 m

Base = 8 m

Answer:

Try relaxing, forget all problems at once, take deep breaths, because if you stress it could cause headaches. Listen to calming music, take a break every once in while. Try not to focus on the bad things that happened in your past! Focus on the good things in future that your smartness is allowing you to achieve! Trust me focusing on the bad things in life cause major headaches...never look back always look forward
