How do you solve x2-3x-28 equals 0?

You can use the quadratic formula for an equation of the form a*x^2 + b*x + c = 0. x = (-b +/- sqrt(b^2-4*a*c))/(2*a) In this case: a = 1 b = -3 c = -28 x = (3 +/- sqrt(9 - 4*(-28)))/2 x = (3 +/- sqrt(121))/2 x = (3 +/- 11)/2 x = 7 or -4 Another option is to attempt to simplify the equation into the form (x-a)(x-b) = 0. Sometimes you can do this by observation. For example: 28 = 4*7 7-4 = 3 Thus: (x-7)(x+4)=0 In this case, a and b are known as the "roots" of the equation, with a = 7 and b = -4.


How to solve x to the third times x to the fourth?

Use x^a * x^b = x^(a+b). x^3 * x^4 = x^7


What is the exponent form for 2x2x2x2?

A number a multiplied b times (so a x a is b=2, a x a x a is b=3, a x a x a x a is b = 4, and so on) is written as ab. Since 2 is multiplied 4 times, you have 24.


What property is (4 3) 12 12 (4 3)?

a(b + c) = ab + ac 4 x 53 = 4(50 + 3) = (4 x 50) + (4 x 3) = 200 + 12 = 212


A florist has 6 banksias 5 wattles and 4 waratahs all the flowers of each kind are different. In how many ways can she make a bunch of 10 flowers if she has to use at least 3 of each kind. 1200?

Must split 4-3-3. Banksia: 3 from 6 = 20, 4 from 6 = 15 Wattles: 3 from 5 = 10, 4 from 5 = 5 Waratahs: 3 from 4 = 4, 4 from 4 = 1 Possible combinations: 4 x B, 3 x each W: 15 x 10 x 4 = 600 4 x Wat, 3 each B & War: 5 x 20 x 4 = 400 4 x War, 3 each B & Wat: 1 x 20 x 10 = 200 Your 1200 is correct.


What are factors in an expression?

Factors aremultiplicativeterms (i.e., they multiply into all the terms). The easiest way to see this is by example.Example 1:a(b+cd)a is a factor and (b+cd) is a factorExample 2:x2 - 9 = (x-3)(x+3)(x-3) is a factor and (x+3) is a factorHopefully you are beginning to notice you can always wrap parenthesis around a factor without altering the order of operations.Example 3:2a(b)(9n-x)+8This is a trick one, but you can factor out a 2:2a(b)(9n-x)+8 = (1)(2)a(b)(9n-x)+(4)(2) = (2)(ab(9n-x)+4)The factors are: 2 and (ab(9n-x)+4)Example 4:If that +8 wasn't on example 3, what would the factors be?2a(b)(9n-x)They would be:2, a, b, and (9n-x)


How do you Calculate any five from eleven?

Any b from a is calculated as:a!/((a-b)!) x b!The ! sign indicates factorial. In your question a = 11 & b = 5In full the formula gives (11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2)/((6 x 5 x 4 x 3 x 2)(5 x 4 x 3 x 2)This simplifies a bit to (11 x 10 x 9 x 8 x 7)/(5 x 4 x 3 x 2) ie 55440/120 = 462.If they can be in any order then you have to multiply by 120...


Which equation describes the line with a slope of 2 and contains the point (4-3)?

The equation of a line with slope m through a point (x0, y0) has equation: y - y0 = m(x - x0) Thus the equation of the line with slope 2 through the point (4, -3) has equation: y - (-3) = 2(x - 4) → y + 3 = 2x - 8 → y = 2x - 11


How do you subtract fractions butterfly method?

For the denominator, multiply the denominators together. For the numerator, subtract the second numerator multiplied by the first denominator from the first numerator multiplied by the second denominator: a/b - p/q = (a x q - b x p)/b x q eg: 6/7 - 3/4 = (6 x 4 - 7 x 3)/7 x 4 = (24 - 21)/28 = 3/28


When is the magnitude of A plus B equal to the magnitude of A B?

a + b = ab a = ab - b = b(a - 1) b = a / (a-1) Any pair of numbers that satisfy that equation, e.g. a = 3, b = 1½ . . . because 3 + 1½ = 4½ and 3 x 1½ = 4½ another example: a = 101, b = 1.01 because 101 + 1.01 = 102.01, and 101 x 1.01 = 102.01


How do you write the equation of the line in standard form through 4 and 0 and 0 and 3?

In y=mx + b form, y = (-3/4)x - 3 - Found the slope (m) to be -3/4 - Substituted slope and a point into y = mx + b to find y-intercept (b). - b = - 3 , Substitute b and m into y=mx+b
