Answer:
(y-2) (y+15) or (y+15) (y-2) either way
Step-by-step explanation:
y^2+13y-30
y^2+15y-2y-30
y(y+15)-2(y+15)
(y+15) (y-2)
Answer:
12
Step-by-step explanation:
5^2 + x^2 = 13^2
x = 12
Answer:
<h3>x = -3 , x = 3</h3>
Step-by-step explanation:
7x² - 3 = 60
7x² - 3 - 60 = 0
7x² - 63 = 0
Simplify the terms
Divide both terms by 7
That's
x² - 9 = 0
Solve the quadratic equation
Use difference of two squares
That's
a² - b² = ( a + b)(a - b)
x² - 9 = 0
(x + 3)(x - 3) = 0
x + 3 = 0 x - 3 = 0
x = - 3 x = 3
Hope this helps you
