<span>2x^2-x=3
</span><span>2x^2-x - 3 = 0
</span><span>(2x - 3)(x + 1) = 0
2x - 3 =0
x = 3/2
x + 1 =0
x = -1
answer
</span>
x = -1 and x = 3/2
Sin(D) = 24/25
tan(D) = 24/7
sin(E) = 7/25
Answer:
-2x^4 +10x^3 -3x^2 +5x +27
Step-by-step explanation:
a) Using the distributive property, we can eliminate parentheses:
2x^4 + 7x^3 - 3x^2 + 7 - 4x^4 + 3x^3 + 5x + 20
And using the distributive property again, we can factor pairs of like terms:
= x^4(2 -4) +x^3(7 +3) -3x^2 +5x +(7 +20)
b)
= -2x^4 +10x^3 -3x^2 +5x +27
