Factorise 18u²-50y completely.

Rufina [12.5K]

Answer:

$2(3u + 5 \sqrt{y} )(3u - 5 \sqrt{y} )$

Step-by-step explanation:

$18 {u}^{2} - 50y \\ \\ = 2[9 {u}^{2} - 25y] \\ \\ = 2[(3 {u})^{2} - (5 \sqrt{y} )^{2} ] \\ \\ = 2(3u + 5 \sqrt{y} )(3u - 5 \sqrt{y} )$

What is 9/16 + 1/2 simplified

trasher [3.6K]

$\frac{9}{16}$ + $\frac{1}{2}$

First, find the least common denominator (LCD) of the two fractions.
Multiples of 16: 16
Multiples of 2: 2, 4, 6, 8, 10, 12, 14, 16
The LCD is 16.
Second, make the denominators the same as the LCD. / Your problem should look like: $\frac{9}{16}$ + $\frac{1x8}{2x8}$
Third, simplify. The denominators are now the same. / Your problem should look like: $\frac{9}{16}$ + $\frac{8}{16}$
Fourth, join the denominators. / Your problem should look like: $\frac{9+8}{16}$
Fifth, simplify. / Your problem should look like: $\frac{17}{16}$
Sixth, convert to mixed fraction. / Your problem should look like: $1 \frac{1}{16}$

Answer: $1\frac{1}{16}$

Solve by factoring. a^2+2a-35=0

sammy [17]

$\displaystyle\bf\\a^2+2a-35=0\\\\a^2\underbrace{-5a+5a}+2a-35=0\\\\a^2-5a+7a-35=0\\\\a(a-5)+7(a-5)=0\\\\(a-5)(a+7)=0\\\\\implies~~a-5=0~~or~~a + 7=0\\\\a-5=0~~\implies~~\boxed{\bf a_1=5}\\ \\a+7=0~~\implies~~\boxed{\bf a_2=-7}$
