Answer:

x = \frac{3}{4} , x = 5

Step-by-step explanation:

4x² - 23x + 15 = 0

Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 4 × 15 = 60 and sum = - 23

The factors are - 20 and - 3

Use these factors to split the x- term

4x² - 20x - 3x + 15 = 0 ( factor the first/second and third/fourth terms )

4x(x - 5) - 3(x - 5) = 0 ← factor out (x - 5) from each term

(x - 5)(4x - 3) = 0

Equate each factor to zero and solve for x

x - 5 = 0 ⇒ x = 5

4x - 3 = 0 ⇒ 4x = 3 ⇒ x = \frac{3}{4}

I need help working question 8. I don't understand how to start it
Lina20 [59]
Why don't you first try to use the cosine law to solve for an angle and then make use of the sin law to solve for the remaining angles.

Cosine law

C^2 = A^2 + B^2 - 2AB(cos C)
Solve for cos C, and then take the inverse of the trig ratio to solve for the angle.

Then set up a proportion like you have done using the sin law and solve for another angle. Knowing the sum of all angles in a triangle add up to 180 degrees, we can easily solve for the remaining angle.
